A mobile driver’s license (often called an mDL) is a version of your ID that you keep on your phone instead of in your pocket. In theory, it would work wherever your regular ID works—TSA, liquor stores, to pick up a prescription, or to get into a bar. This sounds simple enough, and might even be appealing—especially if you’ve ever forgotten or lost your wallet. But there are a few questions you should ask yourself before tossing your wallet into the sea and wandering the earth with just your phone in hand.

In the United States, some proponents of digital IDs promise a future where you can present your phone to a clerk or bouncer and only reveal the information they need—your age—without revealing anything else. They imagine everyone whipping through TSA checkpoints with ease and enjoying simplified applications for government benefits. They also see it as a way to verify identity on the internet, a system that likely censors everyone.

There are real privacy and security trade-offs with digital IDs, and it’s not clear if the benefits are big enough—or exist at all—to justify them.

But if you are curious about this technology, there are still a few things you should know and some questions to consider.

Questions to Ask Yourself

Can I even use a Digital ID anywhere? 

The idea of being able to verify your age by just tapping your phone against an electronic reader—like you may already do to pay for items—may sound appealing. It might make checking out a little faster. Maybe you won’t have to worry about the bouncer at your favorite bar creepily wishing you “happy birthday,” or noting that they live in the same building as you.

Most of these use cases aren’t available yet in the United States. While there are efforts to enable private businesses to read mDLs, these credentials today are mainly being used at TSA checkpoints.

For example, in California, only a small handful of convenience stores in Sacramento and Los Angeles currently accept digital IDs for purchasing age-restricted items like alcohol and tobacco. TSA lists airports that support mobile driver’s licenses, but it only works for TSA PreCheck and only for licenses issued in eleven states.

Also, “selective disclosure,” like revealing just your age and nothing else, isn’t always fully baked. When we looked at California’s mobile ID app, this feature wasn’t available in the mobile ID itself, but rather, it was part of the TruAge addon. Even if the promise of this technology is appealing to you, you might not really be able to use it.

Is there a law in my state about controlling how police officers handle digital IDs?

One of our biggest concerns with digital IDs is that people will unlock their phones and hand them over to police officers in order to show an ID. Ordinarily, police need a warrant to search the content of our phones, because they contain what the Supreme Court has properly called “the privacies of life.”

There are some potential technological protections. You can technically get your digital ID read or scanned in the Wallet app on your phone, without unlocking the device completely. Police could also have a special reader like at some retail stores.

But it’s all too easy to imagine a situation where police coerce or trick someone into unlocking their phone completely, or where a person does not even know that they just need to tap their phone instead of unlocking it. Even seasoned Wallet users screw up payment now and again, and doing so under pressure amplifies that risk. Handing your phone over to law enforcement, either to show a QR code or to hold it up to a reader, is also risky since a notification may pop up that the officer could interpret as probable cause for a search.

Currently, there are few guardrails for how law enforcement interacts with mobile IDs. Illinois recently passed a law that at least attempts to address mDL scenarios with law enforcement, but as far as we know it’s the only state to do anything so far.

At the very minimum, law enforcement should be prohibited from leveraging an mDL check to conduct a phone search.

Is it clear what sorts of tracking the state would use this for?

Smartphones have already made it significantly easier for governments and corporations to track everything we do and everywhere we go. Digital IDs are poised to add to that data collection, by increasing the frequency that our phones leave digital breadcrumbs behind us. There are technological safeguards that could reduce these risks, but they’re currently not required by law, and no technology fix is perfect enough to guarantee privacy.

For example, if you use a digital ID to prove your age to buy a six-pack of beer, the card reader’s verifier might make a record of the holder’s age status. Even if personal information isn’t exchanged in the credential itself, you may have provided payment info associated with this transaction. This collusion of personal information might be then sold to data brokers, seized by police or immigration officials, stolen by data thieves, or misused by employees.

This is just one more reason why we need a federal data privacy law: currently, there aren’t sufficient rules around how your data gets used.

Do I travel between states often?

Not every state offers or accepts digital IDs, so if you travel often, you’ll have to carry a paper ID. If you’re hoping to just leave the house, hop on a plane, and rent a car in another state without needing a wallet, that’s likely still years away.

How do I feel about what this might be used for online?

Mobile driver’s licenses are a clear fit for online age verification schemes. The privacy harms of these sorts of mandates vastly outweigh any potential benefit. Just downloading and using a mobile driver’s license certainly doesn’t mean you agree with that plan, but it’s still good to be mindful of what the future might entail.

Am I being asked to download a special app, or use my phone’s built-in Wallet?

Both Google and Apple allow a few states to use their Wallet apps directly, while other states use a separate app. For Google and Apple’s implementations, we tend to have better documentation and a more clear understanding of how data is processed. For apps, we often know less.

In some cases, states will offer Apple and Google Wallet support, while also providing their own app. Sometimes, this leads to different experiences around where a digital ID is accepted. For example, in Colorado, the Apple and Google Wallet versions will get you through TSA. The Colorado ID app cannot be used at TSA, but can be used at some traffic stops, and to access some services. Conversely, California’s mobile ID comes in an app, but also supports Apple and Google Wallets. Both California’s app and the Apple and Google Wallets are accepted at TSA.

Apps can also come and go. For example, Florida removed its app from the Apple App Store and Google Play Store completely. All these implementations can make for a confusing experience, where you don’t know which app to use, or what features—if any—you might get.

The Right to Paper

For now, the success or failure of digital IDs will at least partially be based on whether people show interest in using them. States will likely continue to implement them, and while it might feel inevitable, it doesn’t have to be. There are countless reasons why a paper ID should continue to be accepted. Not everyone has the resources to own a smartphone, and not everyone who has a smartphone wants to put their ID on it. As states move forward with digital ID plans, privacy and security are paramount, and so is the right to a paper ID.

Note: The Real ID Modernization Act provides one protection for using a mDL we initially missed in this blog post: if you present your phone to federal law enforcement, it cannot be construed as consent to seize or search the device.

We’re happy to see that Discord will soon start offering a form of end-to-end encryption dubbed “DAVE” for its voice and video chats. This puts some of Discord’s audio and video offerings in line with Zoom, and separates it from tools like Slack and Microsoft Teams, which do not offer end-to-end encryption for video, voice, or any other communications on those apps. This is a strong step forward, and Discord can do even more to protect its users’ communications.

End-to-end encryption is used by many chat apps for both text and video offerings, including WhatsApp, iMessage, Signal, and Facebook Messenger. But Discord operates differently than most of those, since alongside private and group text, video, and audio chats, it also encompasses large scale public channels on individual servers operated by Discord. Going forward, audio and video will be end-to-end encrypted, but text, including both group channels and private messages, will not.

When a call is end-to-end encrypted, you’ll see a green lock icon. While it's not required to use the service, Discord also offers a way to optionally verify that the strong encryption a call is using is not being tampered with or eavesdropped on. During a call, one person can pull up the “Voice Privacy Code,” and send it over to everyone else on the line—preferably in a different chat app, like Signal—to confirm no one is compromising participants’ use of end-to-end encryption. This is a way to ensure someone is not impersonating someone and/or listening in to a conversation.

By default, you have to do this every time you initiate a call if you wish to verify the communication has strong security. There is an option to enable persistent verification keys, which means your chat partners only have to verify you on each device you own (e.g. if you sometimes call from a phone and sometimes from a computer, they’ll want to verify for each).

Key management is a hard problem in both the design and implementation of cryptographic protocols. Making sure the same encryption keys are shared across multiple devices in a secure way, as well as reliably discovered in a secure way by conversation partners, is no trivial task. Other apps such as Signal require some manual user interaction to ensure the sharing of key-material across multiple devices is done in a secure way. Discord has chosen to avoid this process for the sake of usability, so that even if you do choose to enable persistent verification keys, the keys on separate devices you own will be different.

While this is an understandable trade-off, we hope Discord takes an extra step to allow users who have heightened security concerns the ability to share their persistent keys across devices. For the sake of usability, they could by default generate separate keys for each device while making sharing keys across them an extra step. This will avoid the associated risk of your conversation partners seeing you’re using the same device across multiple calls. We believe making the use of persistent keys easier and cross-device will make things safer for users as well: they will only have to verify the key for their conversation partners once, instead of for every call they make.

Discord has performed the protocol design and implementation of DAVE in a solidly transparent way, including publishing the protocol whitepaper, the open-source library, commissioning an audit from well-regarded outside researchers, and expanding their bug-bounty program to include rewarding any security researchers who report a vulnerability in the DAVE protocol. This is the sort of transparency we feel is required when rolling out encryption like this, and we applaud this approach.

But we’re disappointed that, citing the need for content moderation, Discord has decided not to extend end-to-end encryption offerings to include private messages or group chats. In a statement to TechCrunch, they reiterated they have no further plans to roll out encryption in direct messages or group chats.

End-to-end encrypted video and audio chats is a good step forward—one that too many messaging apps lack. But because protection of our text conversations is important and because partial encryption is always confusing for users, Discord should move to enable end-to-end encryption on private text chats as well. This is not an easy task, but it’s one worth doing.

If you listen to any podcast long enough, you will almost certainly hear an advertisement for a Virtual Private Network (VPN). These advertisements usually assert that a VPN is the only tool you need to stop cyber criminals, malware, government surveillance, and online tracking. But these advertisements vastly oversell the benefits of VPNs. The reality is that VPNs are mainly useful for one thing: routing your network connection through a different network. Many people, including EFF, thought that VPNs were also a useful tool for encrypting your traffic in the scenario that you didn’t trust the network you were on, such as at a coffee shop, university, or hacker conference. But new research from Leviathan Security demonstrates a reminder that this may not be the case and highlights the limited use-cases for VPNs.

While online violence is alarmingly common globally, women are often more likely to be the target of mass online attacks, nonconsensual leaks of sensitive information and content, and other forms of online violence. 

This International Women’s Day, visit EFF’s Surveillance Self-Defense (SSD) to learn how to defend yourself and your friends from surveillance. In addition to tutorials for installing and using security-friendly software, SSD walks you through concepts like making a security plan, the importance of strong passwords, and protecting metadata.

1. Make Your Own Security Plan

This IWD, learn what a security plan looks like and how you can build one. Trying to protect your online data—like pictures, private messages, or documents—from everything all the time is impractical and exhausting. But, have no fear! Security is a process, and through thoughtful planning, you can put together a plan that’s best for you. Security isn’t just about the tools you use or the software you download. It begins with understanding the unique threats you face and how you can counter those threats. 

2. Protect Yourself on Social Networks

Depending on your circumstances, you may need to protect yourself against the social network itself, against other users of the site, or both. Social networks are among the most popular websites on the internet. Facebook, TikTok, and Instagram each have over a billion users. Social networks were generally built on the idea of sharing posts, photographs, and personal information. They have also become forums for organizing and speaking. Any of these activities can rely on privacy and pseudonymity. Visit our SSD guide to learn how to protect yourself.

3. Tips for Attending Protests

Keep yourself, your devices, and your community safe while you make your voice heard. Now, more than ever, people must be able to hold those in power accountable and inspire others through the act of protest. Protecting your electronic devices and digital assets before, during, and after a protest is vital to keeping yourself and your information safe, as well as getting your message out. Theft, damage, confiscation, or forced deletion of media can disrupt your ability to publish your experiences, and those engaging in protest may be subject to search or arrest, or have their movements and associations surveilled. 

4. Communicate Securely with Signal or WhatsApp

Everything you say in a chat app should be private, viewable by only you and the person you're talking with. But that's not how all chats or DMs work. Most of those communication tools aren't end-to-end encrypted, and that means that the company who runs that software could view your chats, or hand over transcripts to law enforcement. That's why it's best to use a chat app like Signal any time you can. Signal uses end-to-end encryption, which means that nobody, not even Signal, can see the contents of your chats. Of course, you can't necessarily force everyone you know to use the communication tool of your choice, but thankfully other popular tools, like Apple's Messages, WhatsApp and more recently, Facebook's Messenger, all use end-to-end encryption too, as long as you're communicating with others on those same platforms. The more people who use these tools, even for innocuous conversations, the better.

2. Four Voices You Should Hear this International Women’s Day
3. Four Actions You Can Take To Protect Digital Rights this International Women’s Day

On March 3rd, 2009, we launched Surveillance Self-Defense (SSD). At the time, we pitched it as, "an online how-to guide for protecting your private data against government spying." In the last decade hundreds of people have contributed to SSD, over 20 million people have read it, and the content has nearly doubled in length from 40,000 words to almost 80,000. SSD has served as inspiration for many other guides focused on keeping specific populations safe, and those guides have in turn affected how we've approached SSD. A lot has changed in the world over the last 15 years, and SSD has changed with it. 

The Year Is 2009

Let's take a minute to travel back in time to the initial announcement of SSD. Launched with the support of the Open Society Institute, and written entirely by just a few people, we detailed exactly what our intentions were with SSD at the start:

EFF created the Surveillance Self-Defense site to educate Americans about the law and technology of communications surveillance and computer searches and seizures, and to provide the information and tools necessary to keep their private data out of the government's hands… The Surveillance Self-Defense project offers citizens a legal and technical toolkit with tips on how to defend themselves in case the government attempts to search, seize, subpoena or spy on their most private data.

SSD's design when it first launched in 2009.

To put this further into context, it's worth looking at where we were in 2009. Avatar was the top grossing movie of the year. Barack Obama was in his first term as president in the U.S. In a then-novel approach, Iranians turned to Twitter to organize protests. The NSA has a long history of spying on Americans, but we hadn't gotten to Jewel v. NSA or the Snowden revelations yet. And while the iPhone had been around for two years, it hadn't seen its first big privacy controversy yet (that would come in December of that year, but it'd be another year still before we hit the "your apps are watching you" stage).

Most importantly, in 2009 it was more complicated to keep your data secure than it is today. HTTPS wasn't common, using Tor required more technical know-how than it does nowadays, encrypted IMs were the fastest way to communicate securely, and full-disk encryption wasn't a common feature on smartphones. Even for computers, disk encryption required special software and knowledge to implement (not to mention time, solid state drives were still extremely expensive in 2009, so most people still had spinning disk hard drives, which took ages to encrypt and usually slowed down your computer significantly).

And thus, SSD in 2009 focused heavily on law enforcement and government access with its advice. Not long after the launch in 2009, in the midst of the Iranian uprising, we launched the international version, which focused on the concerns of individuals struggling to preserve their right to free expression in authoritarian regimes.

And that's where SSD stood, mostly as-is, for about six years. 

The Redesigns

In 2014, we redesigned and relaunched SSD with support from the Ford Foundation. The relaunch had at least 80 people involved in the writing, reviewing, design, and translation process. With the relaunch, there was also a shift in the mission as the threats expanded from just the government, to corporate and personal risks as well. From the press release:

"Everyone has something to protect, whether it's from the government or stalkers or data-miners," said EFF International Director Danny O'Brien. "Surveillance Self-Defense will help you think through your personal risk factors and concerns—is it an authoritarian government you need to worry about, or an ex-spouse, or your employer?—and guide you to appropriate tools and practices based on your specific situation."

2014 proved to be an effective year for a major update. After the murders of Michael Brown and Eric Garner, protestors hit the streets across the U.S., which made our protest guide particularly useful. There were also major security vulnerabilities that year, like Heartbleed, which caused all sorts of security issues for website operators and their visitors, and Shellshock, which opened up everything from servers to cameras to bug exploits, ushering in what felt like an endless stream of software updates on everything with a computer chip in it. And of course, there was still fallout from the Snowden leaks in 2013.

In 2018 we did another redesign, and added a new logo for SSD that came along with EFF's new design. This is more or less the same design of the site today.

SSD's current design, which further clarifies what sections a guide is in, and expands the security scenarios.

Perhaps the most notable difference between this iteration of SSD and the years before is the lack of detailed reasoning explaining the need for its existence on the front page. No longer was it necessary to explain why we all need to practice surveillance self-defense. Online surveillance had gone mainstream.

Shifting Language Over the Years

As the years passed and the site was redesigned, we also shifted how we talked about security. In 2009 we wrote about security with terms like, "adversaries," "defensive technology," "threat models," and "assets." These were all common cybersecurity terms at the time, but made security sound like a military exercise, which often disenfranchised the very people who needed help. For example, in the later part of the 2010s, we reworked the idea of "threat modeling," when we published Your Security Plan. This was meant to be less intimidating and more inclusive of the various types of risks that people face.

The advice in SSD has changed over the years, too. Take passwords as an example, where in 2009 we said, "Although we recommend memorizing your passwords, we recognize you probably won't." First off, rude! Second off, maybe that could fly with the lower number of accounts we all had back in 2009, but nowadays nobody is going to remember hundreds of passwords. And regardless, that seems pretty dang impossible when paired with the final bit of advice, "You should change passwords every week, every month, or every year — it all depends on the threat, the risk, and the value of the asset, traded against usability and convenience."

Moving onto 2015, we phrased this same sentiment much differently, "Reusing passwords is an exceptionally bad security practice, because if an attacker gets hold of one password, she will often try using that password on various accounts belonging to the same person… Avoiding password reuse is a valuable security precaution, but you won't be able to remember all your passwords if each one is different. Fortunately, there are software tools to help with this—a password manager."

Well, that's much more polite!

Since then, we've toned that down even more, "Reusing passwords is a dangerous security practice. If someone gets ahold of your password —whether that's from a data breach, or wherever else—they can often gain access to any other account you used that same password. The solution is to use unique passwords everywhere and take additional steps to secure your accounts when possible."

Security is an always evolving process, so too is how we talk about it. But the more people we bring on board, the better it is for everyone. How we talk about surveillance self-defense will assuredly continue to adapt in the future.

Shifting Language(s) Over the Years

Initially in 2009, SSD was only available in English, and soon after launch, in Bulgarian. In the 2014 re-launch, we added Arabic and Spanish. Then added French, Thai, Vietnamese, and Urdu in 2015. Later that year, we added a handful of Amharic translations, too. This was accomplished through a web of people in dozens of countries who volunteered to translate and review everything. Many of these translations were done for highly specific reasons. For example, we had a Google Policy Fellow, Endalk Chala, who was part of the Zone 9 bloggers in Ethiopia. He translated everything into Amharic as he was fighting for his colleagues and friends who were imprisoned in Ethiopia on terrorism charges.

By 2019, we were translating most of SSD into at least 10 languages: Amharic, Arabic, Spanish, French, Russian, Turkish, Vietnamese, Brazilian Portuguese, Thai, and Urdu (as well as additional, externally-hosted community translations in Indonesian Bahasa, Burmese, Traditional Chinese, Igbo, Khmer, Swahili, Yoruba, and Twi).

Currently, we're focusing on getting the entirety of SSD re-translated into seven languages, then focusing our efforts on translating specific guides into other languages. 

Always Updating

Since 2009, we've done our best to review and update the guides in SSD. This has included minor changes to respond to news events, depreciating guides completely when they're no longer applicable in modern security plans, and massive rewrites when technology has changed.

The original version of SSD was launched mostly as a static text (we even offered a printer-friendly version), though updates and revisions did occur, they were not publicly tracked as clearly as they are today. In its early years, SSD was able to provide useful guidance across a number of important events, like Occupy Wall Street, before the major site redesign in 2014, which helped it become more useful training activists, including for Ferguson and Standing Rock, amongst others. The ability to update SSD along with changing trends and needs has ensured it can always be useful as a resource.

That redesign also better facilitated the updates process. The site became easier to navigate and use, and easier to update. For example, in 2017 we took on a round of guide audits in response to concerns following the 2016 election. In 2019 we continued that process with around seven major updates to SSD, and in 2020, we did five. We don't have great stats for 2021 and 2022, but in 2023 we managed 14 major updates or new guides. We're hoping to have the majority of SSD reviewed and revamped by the end of this year, with a handful of expansions along the way.

Which brings us to the future of SSD. We will continue updating, adapting, and adding to SSD in the coming years. It is often impossible to know what will be needed, but rest assured we'll be there to answer that whenever we can. As mentioned above, this includes getting more translations underway, and continuing to ensure that everything is accurate and up-to-date so SSD can remain one of the best repositories of security information available online.

We hope you’ll join EFF in celebrating 15 years of SSD!

Welcome! 

The fact that you’re reading this means that you probably care deeply about the issue of privacy, which warms our hearts. Unfortunately, even though you care about privacy, or perhaps because you care so much about it, you may feel that there's not much you (or anyone) can really do to protect it, no matter how hard you try. Perhaps you think “privacy is dead.” 

We’ve all probably felt a little bit like you do at one time or another. At its worst, this feeling might be described as despair. Maybe it hits you because a new privacy law seems to be too little, too late. Or maybe you felt a kind of vertigo after reading a news story about a data breach or a company that was vacuuming up private data willy-nilly without consent. 

People are angry because they care about privacy, not because privacy is dead.

Even if you don’t have this feeling now, at some point you may have felt—or possibly will feel—that we’re past the point of no return when it comes to protecting our private lives from digital snooping. There are so many dangers out there—invasive governments, doorbell cameras, license plate readers, greedy data brokers, mismanaged companies that haven’t installed any security updates in a decade. The list goes on.

This feeling is sometimes called “privacy nihilism.” Those of us who care the most about privacy are probably more likely to get it, because we know how tough the fight is. 

We could go on about this feeling, because sometimes we at EFF have it, too. But the important thing to get across is that this feeling is valid, but it’s also not accurate. Here’s why.

You Aren’t Fighting for Privacy Alone

For starters, remember that none of us are fighting alone. EFF is one of dozens, if not hundreds,  of organizations that work to protect privacy.  EFF alone has over thirty-thousand dues-paying members who support that fight—not to mention hundreds of thousands of supporters subscribed to our email lists and social media feeds. Millions of people read EFF’s website each year, and tens of millions use the tools we’ve made, like Privacy Badger. Privacy is one of EFF’s biggest concerns, and as an organization we have grown by leaps and bounds over the last two decades because more and more people care. Some people say that Americans have given up on privacy. But if you look at actual facts—not just EFF membership, but survey results and votes cast on ballot initiatives—Americans overwhelmingly support new privacy protections. In general, the country has grown more concerned about how the government uses our data, and a large majority of people say that we need more data privacy protections. 

People are angry because they care about privacy, not because privacy is dead.

Some people also say that kids these days don’t care about their privacy, but the ones that we’ve met think about privacy a lot. What’s more, they are fighting as hard as anyone to stop privacy-invasive bills like the Kids Online Safety Act. In our experience, the next generation cares intensely about protecting privacy, and they’re likely to have even more tools to do so. 

Laws are Making Their Way Around the World

Strong privacy laws don’t cover every American—yet. But take a look at just one example to see how things are improving: the California Consumer Privacy Act of 2018 (CCPA). The CCPA isn’t perfect, but it did make a difference. The CCPA granted Californians a few basic rights when it comes to their relationship with businesses, like the right to know what information companies have about you, the right to delete that information, and the right to tell companies not to sell your information. 

This wasn’t a perfect law for a few reasons. Under the CCPA, consumers have to go company-by-company to opt out in order to protect their data. At EFF, we’d like to see privacy and protection as the default until consumers opt-in. Also, CCPA doesn’t allow individuals to sue if their data is mismanaged—only California’s Attorney General and the California Privacy Protection Agency can do it. And of course, the law only covers Californians. 

Remember that it takes time to change the system.

But this imperfect law is slowly getting better. Just this year California’s legislature passed the DELETE Act, which resolves one of those issues. The California Privacy Protection Agency now must create a deletion mechanism for data brokers that allows people to make their requests to every data broker with a single, verifiable consumer request. 

Pick a privacy-related topic, and chances are good that model bills are being introduced, or already exist as laws in some places, even if they don’t exist everywhere. The Illinois Biometric Information Privacy Act, for example, passed back in 2008, protects people from nonconsensual use of their biometrics for face recognition. We may not have comprehensive privacy laws yet in the US, but other parts of the world—like Europe—have more impactful, if imperfect, laws. We can have a nationwide comprehensive consumer data privacy law, and once those laws are on the books, they can be improved.  

We Know We’re Playing the Long Game

Remember that it takes time to change the system. Today we take many protections for granted, and often assume that things are only getting worse, not better. But many important rights are relatively new. For example, our Constitution didn’t always require police to get a warrant before wiretapping our phones. It took the Supreme Court four decades to get this right. (They were wrong in 1928 in Olmstead, then right in 1967 in Katz.)

Similarly, creating privacy protections in law and in technology is not a sprint. It is a marathon. The fight is long, and we know that. Below, we’ve got examples of the progress that we’ve already made, in law and elsewhere. 

Just because we don’t have some protective laws today doesn’t mean we can’t have them tomorrow. 

Privacy Protections Have Actually Increased Over the Years

The World Wide Web is Now Encrypted 

When the World Wide Web was created, most websites were unencrypted. Privacy laws aren’t the only way to create privacy protections, as the now nearly-entirely encrypted web shows:  another approach is to engineer in strong privacy protections from the start. 

The web has now largely switched from non-secure HTTP to the more secure HTTPS protocol. Before this happened, most web browsing was vulnerable to eavesdropping and content hijacking. HTTPS fixes most of these problems. That's why EFF, and many like-minded supporters, pushed for web sites to adopt HTTPS by default. As of 2021, about 90% of all web page visits use HTTPS. This switch happened in under a decade. This is a big win for encryption and security for everyone, and EFF's Certbot and HTTPS Everywhere are tools that made it happen, by offering an easy and free way to switch an existing HTTP site to HTTPS. (With a lot of help from Let’s Encrypt, started in 2013 by a group of determined researchers and technologists from EFF and the University of Michigan.) Today, it’s the default to implement HTTPS. 

Cell Phone Location Data Now Requires a Warrant

In 2018, the Supreme Court handed down a landmark opinion in Carpenter v. United States, ruling 5-4 that the Fourth Amendment protects cell phone location information. As a result, police must now get a warrant before obtaining this data. 

But where else this ruling applies is still being worked out. Perhaps the most significant part of the ruling is its explicit recognition that individuals can maintain an expectation of privacy in information that they provide to third parties. The Court termed that a “rare” case, but it’s clear that other invasive surveillance technologies, particularly those that can track individuals through physical space, are now ripe for challenge. Expect to see much more litigation on this subject from EFF and our friends.

Americans’ Outrage At Unconstitutional Mass Surveillance Made A Difference

In 2013, government contractor Edward Snowden shared evidence confirming, among other things, that the United States government had been conducting mass surveillance on a global scale, including surveillance of its own citizens’ telephone and internet use. Ten years later, there is definitely more work to be done regarding mass surveillance. But some things are undoubtedly better: some of the National Security Agency’s most egregiously illegal programs and authorities have shuttered or been forced to end. The Intelligence Community has started affirmatively releasing at least some important information, although EFF and others have still had to fight some long Freedom of Information Act (FOIA) battles.

Privacy Options Are So Much Better Today

Remember PGP and GPG? If you do, you know that generally, there are much easier ways to send end-to-end encrypted communications today than there used to be. It’s fantastic that people worked so hard to protect their privacy in the past, and it’s fantastic that they don’t have to work as hard now! (If you aren’t familiar with PGP or GPG, just trust us on this one.) 

Don’t give in to privacy nihilism. Instead, share and celebrate the ways we’re winning. 

Advice for protecting online privacy used to require epic how-to guides for complex tools; now, advice is usually just about what relatively simple tools or settings to use. People across the world have Signal and WhatsApp. The web is encrypted, and the Tor Browser lets people visit websites anonymously fairly easily. Password managers protect your passwords and your accounts; third-party cookie blockers like EFF’s Privacy Badger stop third-party tracking. There are even options now to turn off your Ad ID—the key that enables most third-party tracking on mobile devices—right on your phone. These tools and settings all push the needle forward.

We Are Winning The Privacy War, Not Losing It

Sometimes people respond to privacy dangers by comparing them to sci-fi dystopias. But be honest: most science fiction dystopias still scare the heck out of us because they are much, much more invasive of privacy than the world we live in. 

In an essay called “Stop Saying Privacy Is Dead,” Evan Selinger makes a necessary point: “As long as you have some meaningful say over when you are watched and can exert agency over how your data is processed, you will have some modicum of privacy.” 

Of course we want more than a modicum of privacy. But the point here is that many of us generally do get to make decisions about our privacy. Not all—of course. But we all recognize that there are different levels of privacy in different places, and that privacy protections aren’t equally good or bad no matter where we go. We have places we can go—online and off—that afford us more protections than others. And because of this, most of the people reading this still have deep private lives, and can choose, with varying amounts of effort, not to allow corporate or government surveillance into those lives. 

Worrying about every potential threat, and trying to protect yourself from each of them, all of the time, is a recipe for failure.

Privacy is a process, not a single thing. We are always negotiating what levels of privacy we have. We might not always have the upper hand, but we are often able to negotiate. This is why we still see some fictional dystopias and think, “Thank God that’s not my life.” As long as we can do this, we are winning. 

“Giving Up” On Privacy May Not Mean Much to You, But It Does to Many

Shrugging about the dangers of surveillance can seem reasonable when that surveillance isn’t very impactful on our lives. But for many, fighting for privacy isn't a choice, it is a means to survive. Privacy inequity is real; increasingly, money buys additional privacy protections. And if privacy is available for some, then it can exist for all. But we should not accept that some people will have privacy and others will not. This is why digital privacy legislation is digital rights legislation, and why EFF is opposed to data dividends and pay-for-privacy schemes.

Privacy increases for all of us when it increases for each of us. It is much easier for a repressive government to ban end-to-end encrypted messengers when only journalists and activists use them. It is easier to know who is an activist or a journalist when they are the only ones using privacy-protecting services or methods. As the number of people demanding privacy increases, the safer we all are. Sacrificing others because you don't feel the impact of surveillance is a fool's bargain. 

Time Heals Most Privacy Wounds

You may want to tell yourself: companies already know everything about me, so a privacy law a year from now won't help. That's incorrect, because companies are always searching for new data. Some pieces of information will never change, like our biometrics. But chances are you've changed in many ways over the years—whether that's as big as a major life event or as small as a change in your tastes in movies—but who you are today is not necessarily you'll be tomorrow.

As the source of that data, we should have more control over where it goes, and we’re slowly getting it. But that expiration date means that even if some of our information is already out there, it’s never going to be too late to shut off the faucet. So if we pass a privacy law next year, it’s not the case that every bit of information about you has already leaked, so it won’t do any good. It will.

What To Do When You Feel Like It’s Impossible

It can feel overwhelming to care about something that feels like it’s dying a death of a thousand cuts. But worrying about every potential threat, and trying to protect yourself from each of them, all of the time, is a recipe for failure. No one really needs to be vigilant about every threat at all times. That’s why our recommendation is to create a personalized security plan, rather than throwing your hands up or cowering in a corner. 

Once you’ve figured out what threats you should worry about, our advice is to stay involved. We are all occasionally skeptical that we can succeed, but taking action is a great way to get rid of that gnawing feeling that there’s nothing to be done. EFF regularly launches new projects that we hope will help you fight privacy nihilism. We’re in court many times a year fighting privacy violations. We create ways for like-minded, privacy-focused people to work together in their local advocacy groups, through the Electronic Frontier Alliance, our grassroots network of community and campus organizations fighting for digital rights. We even help you teach others to protect their own privacy. And of course every day is a good day for you to join us in telling government officials and companies that privacy matters. 

We know we can win because we’re creating the better future that we want to see every day, and it’s working. But we’re also building the plane while we’re flying it. Just as the death of privacy is not inevitable, neither is our success. It takes real work, and we hope you’ll help us do that work by joining us. Take action. Tell a friend. Download Privacy Badger. Become an EFF member. Gift an EFF membership to someone else.

Don’t give in to privacy nihilism. Instead, share and celebrate the ways we’re winning. 

The latest version of Privacy Badger 1 replaces embedded tweets with click-to-activate placeholders. This is part of Privacy Badger's widget replacement feature, where certain potentially useful widgets are blocked and then replaced with placeholders. This protects privacy by default while letting you restore the original widget whenever you want it or need it for the page to function.

Websites often include external elements such as social media buttons, comments sections, and video players. Although potentially useful, these “widgets” often track your behavior. The tracking happens regardless of whether you click on the widget. If you see a widget, the widget sees you back.

This is where Privacy Badger's widget replacement comes in. When blocking certain social buttons and other potentially useful widgets, Privacy Badger replaces them with click-to-activate placeholders. You will not be tracked by these replacements unless you explicitly choose to activate them.

Privacy Badger’s placeholders tell you exactly what happened while putting you in control.

Changing the UI of a website is a bold move for a browser extension to do. That’s what Privacy Badger is all about though: making strong choices on behalf of user privacy and revealing how that privacy is betrayed by businesses online.

Privacy Badger isn’t the first software to replace embedded widgets with placeholders for privacy or security purposes. As early as 2004, users could install Flashblock, an extension that replaced embedded Adobe Flash plugin content, a notoriously insecure technology.

Flashblock’s Flash plugin placeholders lacked user-friendly buttons but got the (Flash blocking) job done.

Other extensions and eventually, even browsers, followed Flashblock in offering similar plugin-blocking placeholders. The need to do this declined as plugin use dropped over time, but a new concern rose to prominence. Privacy was under attack as social media buttons started spreading everywhere.

This brings us to ShareMeNot. Developed in 2012 as a research tool to investigate how browser extensions might enforce privacy on behest of the user, ShareMeNot replaced social media “share” buttons with click-to-activate placeholders. In 2014, ShareMeNot became a part of Privacy Badger. While the emphasis has shifted away from social media buttons to interactive widgets like video players and comments sections, Privacy Badger continues to carry on ShareMeNot's legacy.

Unfortunately, widget replacement is not perfect. The placeholder’s buttons may not work sometimes, or the placeholder may appear in the wrong place or may fail to appear at all. We will keep fixing and improving widget replacement. You can help by letting us know when something isn’t working right.

To report problems, first click on Privacy Badger’s icon in your browser toolbar. Privacy Badger’s “popup” window will open. Then, click the “Report broken site” button in the popup.

Pro tip #1: Because our YouTube replacement is not quite ready to be enabled by default, embedded YouTube players are not yet blocked or replaced. If you like though, you can try our YouTube replacement now.

To opt in, visit Privacy Badger's options page, select the “Tracking Domains” tab, search for “youtube.com”, and move the toggle for youtube.com to the “Block entirely” position.

Pro tip #2: The most private way to activate a replaced widget is to use the “this [YouTube] widget” link (inside the “Privacy Badger has replaced this [YouTube] widget” text), when the link is available. Going through the link, as opposed to one of the Allow buttons, means the widget provider doesn't necessarily get to know what site you activated the widget on. You can also right-click the link to save the widget URL; no need to visit the link or to use browser developer tools.

Click the link to open the widget in a new tab.

Privacy tools should be measured not only by efficacy, but also ease of use. As we write in the FAQ, we want Privacy Badger to function well without any special knowledge or configuration by the user. Privacy should be made easy, rather than gatekept for “power users.” Everyone should be able to decide for themselves when and with whom they want to share information. Privacy Badger fights to restore this control, biting back at sneaky non-consensual surveillance.

• 1. Privacy Badger version 2023.12.1

It's been a big year for Surveillance Self-Defense (SSD), our repository of self-help resources for helping better protect you and your friends from online spying. We've done a number of updates and tackled a few new emerging topics with blog posts.

Fighting for digital security and privacy rights is important, but sometimes we all just need to know what steps we can take to minimize spying, and when steps aren't possible, explaining how things work to help keep you safe. To do this, we break SSD into four sections:

• Basics: A starter resource that includes overviews of how digital surveillance works.
• Tool Guides: Step-by-step tutorials on using privacy and security tools.
• Further Learning: Explainers about protecting your digital privacy.
• Security Scenarios: Playlists of our resources for specific use cases, such as LGBTQ+ youth, journalists, activists, and more.

But not everything makes sense in SSD, so sometimes we also tackle security education issues with blogs, which tend to focus more on news events or new technology that may not have rolled out widely yet. Each has its place, and each saw a variety of new guidance this year.

Re-tooling Our SSD Tool Guides

Surveillance Self-Defense has provided expert guidance for security and privacy for 14 years. And in those years it has seen a number of revisions, expansions, and changes. We try to consistently audit and update SSD so it contains up to date information. Each guide has a "last reviewed" date so you can quickly see at the start when it last got an expert review.

This year we tackled a number of updates, and took the time to take a new approach with two of our most popular guides: Signal and WhatsApp. For these, we combined the once-separate Android and iPhone guides into one, making them easier to update (and translate) in the future.

We also updated many other guides this year with new information, screenshots, and advice:

• Creating Strong Passwords
• Your Security Plan
• Attending a Protest
• Choosing a VPN That's Right for You
• Facebook Groups: Reducing Risks
• Protecting Yourself on Social Networks
• Abortion Access Activist, Worker, or Patient
• How to: Use Tor for Linux
• How to: Use Tor for Windows
• How to: Use Tor for macOS

SSD also received two new guides. The first was a new guide for choosing a password manager, one of the most important security tools, and one that can be overwhelming to research and start using. The second was a guide for using Tor on mobile devices, which is an increasingly useful place to use the privacy-protecting software.

Providing New Guidance and Responding to News

Part of security education is explaining new and old technologies, responding to news events, and laying out details of any technological quirks we find. For this, we tend to turn to our blog instead of SSD. But the core idea is the same: provide self-help guidance for navigating various security and privacy concerns.

We came up with guidance for passkeys, a new type of login that eliminates the need for passwords altogether. Passkeys can be confusing, both from a security perspective and from a basic usability perspective. We do think there's work that can be done to improve them, and like most security advice, the answer to the question of whether you should use them is "it depends." But for many people, if you’re not already using a password manager, passkeys will be a tremendous increase in security.

When it comes to quirks in apps, we took a look at what happens when you delete a replied-to message in encrypted messaging apps. There are all sorts of little oddities with end-to-end encrypted messaging apps that are worth being aware of. While they don't compromise the integrity of the messaging—your communications are safe from the companies that run them—they can sometimes act unexpectedly, like keeping a message you deleted around longer than you may realize if someone in the chat replied to it directly.

The DNA site 23andMe suffered a “credential stuffing” attack that resulted in 6.9 million user's data appearing on hacker forums. There were only a relatively small number of accounts actually compromised, but once in, the attacker was able to scrape information about other users using a feature known as DNA Relatives, which provided users with an expansive family tree. There's nothing you can do after this if your data was included, but we explained what happened, and the handful of steps you could take to better secure your account and make it more private in the future.

Google released its "Privacy Sandbox" feature, which, while improved from initial proposals back in 2019, still tracks your internet use for behavioral advertising by using your web browsing to define "topics" of interest, then queuing up ads based on those interests. The idea is that instead of the dozens of third-party cookies placed on websites by different advertisers and tracking companies, Google itself will track your interests in the browser itself, controlling even more of the advertising ecosystem than it already does. Our blog shows you how to disable it, if you choose to.

We also took a deep dive into an Android tablet meant for kids that turned out to be filled with sketchyware. The tablet was riddled with all sorts of software we didn't like, but we shared guidance for how to better secure an Android tablet—all steps worth taking before you hand over any Android tablet as a holiday gift.

After a hard fought battle pushing Apple to encrypt iCloud backups, the company actually took it a step further, allowing you to encrypt nearly everything in iCloud, including those backups, with a new feature they call Advanced Data Protection. Unfortunately, it's not the default setting, so you should enable it for yourself as soon as you can.

Similarly, Meta finally rolled out end-to-end encryption for Messenger, which is thankfully enabled by default, though there are some quirks with how backups work that we explain in this blog post.

EFF worked hard in 2023 to explain new consumer security technologies, provide guidance for tools, and help everyone communicate securely. There's plenty more work to be done next year, and we'll be here to explain what you can, how to do it, and how it works in 2024.

This blog is part of our Year in Review series. Read other articles about the fight for digital rights in 2023.

Both OpenAI and Google have released guidance for website owners who do not want the two companies using the content of their sites to train the company's large language models (LLMs). We've long been supporters of the right to scrape websites—the process of using a computer to load and read pages of a website for later analysis—as a tool for research, journalism, and archivers. We believe this practice is still lawful when collecting training data for generative AI, but the question of whether something should be illegal is different from whether it may be considered rude, gauche, or unpleasant. As norms continue to develop around what kinds of scraping and what uses of scraped data are considered acceptable, it is useful to have a tool for website operators to automatically signal their preference to crawlers. Asking OpenAI and Google (and anyone else who chooses to honor the preference) to not include scrapes of your site in its models is an easy process as long as you can access your site's file structure.

We've talked before about how these models use art for training, and the general idea and process is the same for text. Researchers have long used collections of data scraped from the internet for studies of censorship, malware, sociology, language, and other applications, including generative AI. Today, both academic and for-profit researchers collect training data for AI using bots that go out searching all over the web and “scrape up” or store the content of each site they come across. This might be used to create purely text-based tools, or a system might collect images that may be associated with certain text and try to glean connections between the words and the images during training. The end result, at least currently, is the chatbots we've seen in the form of Google Bard and ChatGPT.

It would ease many minds for other companies with similar AI products, like Anthropic, Amazon, and countless others, to announce that they'd respect similar requests.

If you do not want your website's content used for this training, you can ask the bots deployed by Google and Open AI to skip over your site. Keep in mind that this only applies to future scraping. If Google or OpenAI already have data from your site, they will not remove it. It also doesn't stop the countless other companies out there training their own LLMs, and doesn't affect anything you've posted elsewhere, like on social networks or forums. It also wouldn't stop models that are trained on large data sets of scraped websites that aren't affiliated with a specific company. For example, OpenAI's GPT-3 and Meta's LLaMa were both trained using data mostly collected from Common Crawl, an open source archive of large portions of the internet that is routinely used for important research. You can block Common Crawl, but doing so blocks the web crawler from using your data in all its data sets, many of which have nothing to do with AI.

There's no technical requirement that a bot obey your requests. Currently only Google and OpenAI who have announced that this is the way to opt-out, so other AI companies may not care about this at all, or may add their own directions for opting out. But it also doesn't block any other types of scraping that are used for research or for other means, so if you're generally in favor of scraping but uneasy with the use of your website content in a corporation's AI training set, this is one step you can take.

Before we get to the how, we need to explain what exactly you'll be editing to do this.

What's a Robots.txt?

In order to ask these companies not to scrape your site, you need to edit (or create) a file located on your website called "robots.txt." A robots.txt is a set of instructions for bots and web crawlers. Up until this point, it was mostly used to provide useful information for search engines as their bots scraped the web. If website owners want to ask a specific search engine or other bot to not scan their site, they can enter that in their robots.txt file. Bots can always choose to ignore this, but many crawling services respect the request.

This might all sound rather technical, but it's really nothing more than a small text file located in the root folder of your site, like "https://www.example.com/robots.txt." Anyone can see this file on any website. For example, here's The New York Times' robots.txt, which currently blocks both ChatGPT and Bard. 

If you run your own website, you should have some way to access the file structure of that site, either through your hosting provider's web portal or FTP. You may need to comb through your provider's documentation for help figuring out how to access this folder. In most cases, your site will already have a robots.txt created, even if it's blank, but if you do need to create a file, you can do so with any plain text editor. Google has guidance for doing so here.

EFF will not be using these flags because we believe scraping is a powerful tool for research and access to information.

What to Include In Your Robots.txt to Block ChatGPT and Google Bard

With all that out of the way, here's what to include in your site's robots.txt file if you do not want ChatGPT and Google to use the contents of your site to train their generative AI models. If you want to cover the entirety of your site, add these lines to your robots.txt file:

ChatGPT

User-agent: GPTBot

Disallow: /

Google Bard

User-agent: Google-Extended

Disallow: /

You can also narrow this down to block access to only certain folders on your site. For example, maybe you don't mind if most of the data on your site is used for training, but you have a blog that you use as a journal. You can opt out specific folders. For example, if the blog is located at yoursite.com/blog, you'd use this:

ChatGPT

User-agent: GPTBot

Disallow: /blog

Google Bard

User-agent: Google-Extended

Disallow: /blog

As mentioned above, we at EFF will not be using these flags because we believe scraping is a powerful tool for research and access to information; we want the information we’re providing to spread far and wide and to be represented in the outputs and answers provided by LLMs. Of course, individual website owners have different views for their blogs, portfolios, or whatever else you use your website for. We're in favor of means for people to express their preferences, and it would ease many minds for other companies with similar AI products, like Anthropic, Amazon, and countless others, announce that they'd respect similar requests.

With the holidays upon us, it's easy to default to giving the tech gifts that retailers tend to push on us this time of year: smart speakers, video doorbells, bluetooth trackers, fitness trackers, and other connected gadgets are all very popular gifts. But before you give one, think twice about what you're opting that person into.

A number of these gifts raise red flags for us as privacy-conscious digital advocates. Ring cameras are one of the most obvious examples, but countless others over the years have made the security or privacy naughty list (and many of these same electronics directly clash with your right to repair).

One big problem with giving these sorts of gifts is that you're opting another person into a company's intrusive surveillance practice, likely without their full knowledge of what they're really signing up for.

For example, a smart speaker might seem like a fun stocking stuffer. But unless the giftee is tapped deeply into tech news, they likely don't know there's a chance for human review of any recordings. They also may not be aware that some of these speakers collect an enormous amount of data about how you use it, typically for advertising–though any connected device might have surprising uses to law enforcement, too.

There's also the problem of tech companies getting acquired like we've seen recently with Tile, iRobot, or Fitbit. The new business can suddenly change the dynamic of the privacy and security agreements that the user made with the old business when they started using one of those products.

And let's not forget about kids. Long subjected to surveillance from elves and their managers, electronics gifts for kids can come with all sorts of surprise issues, like the kid-focused tablet we found this year that was packed with malware and riskware. Kids’ smartwatches and a number of connected toys are also potential privacy hazards that may not be worth the risks if not set up carefully.

Of course, you don't have to avoid all technology purchases. There are plenty of products out there that aren't creepy, and a few that just need extra attention during set up to ensure they're as privacy-protecting as possible. 

What To Do Instead

While we don't endorse products, you don't have to start your search in a vacuum. One helpful place to start is Mozilla's Privacy Not Included gift guide, which provides a breakdown of the privacy practices and history of products in a number of popular gift categories. This way, instead of just buying any old smart-device at random because it's on sale, you at least have the context of what sort of data it might collect, how the company has behaved in the past, and what sorts of potential dangers to consider. U.S. PIRG also has guidance for shopping for kids, including details about what to look for in popular categories like smart toys and watches.

Finally, when shopping it's worth keeping in mind two last details. First, some “smart” devices can be used without their corresponding apps, which should be viewed as a benefit, because we've seen before that app-only gadgets can be bricked by a shift in company policies. Also, remember that not everything needs to be “smart” in the first place; often these features add little to the usability of the product.

Your job as a privacy-conscious gift-giver doesn't end at the checkout screen.

If you're more tech savvy than the person receiving the item, or you're helping set up a gadget for a child, there's no better gift than helping set it up as privately as possible. Take a few minutes after they've unboxed the item and walk through the set up process with them. Some options to look for: 

• Enable two-factor authentication when available to help secure their new account.
• If there are any social sharing settings—particularly popular with fitness trackers and game consoles—disable any unintended sharing that might end up on a public profile.
• Look for any options to enable automatic updates. This is usually enabled by default these days, but it's always good to double-check.
• If there's an app associated with the new device (and there often is), help them choose which permissions to allow, and which to deny. Keep an eye out for location data, in particular, especially if there's no logical reason for the app to need it. 
• While you're at it, help them with other settings on their phone, and make sure to disable the phone’s advertising ID.
• Speaking of advertising IDs, some devices have their own advertising settings, usually located somewhere like, Settings > Privacy > Ad Preferences. If there's an option to disable any ad tracking, take advantage of it. While you're in the settings, you may find other device-specific privacy or data usage settings. Take that opportunity to opt out of any tracking and collection when you can. This will be very device-dependent, but it's especially worth doing on anything you know tracks loads of data, like smart TVs. 
• If you're helping set up a video or audio device, like a smart speaker or robot vacuum, poke around in the options to see if you can disable any sort of "human review" of recordings.

If during the setup process, you notice some gaps in their security hygiene, it might also be a great opportunity to help them set up other security measures, like setting up a password manager. 

Giving the gift of electronics shouldn’t come with so much homework, but until we have a comprehensive data privacy law, we'll likely have to contend with these sorts of set-up hoops. Until that day comes, we can all take the time to help those who need it.

After finding risky software on an Android (Google’s mobile operating system) device marketed for kids, we wanted to put together some tips to help better secure your kid's Android device (and even your own). Despite the dangers that exist, there are many things that can be done to at least mitigate harm and assist parents and children. There are also safety tools that your child can use at their own discretion.

There's a handful of different tools, settings, and apps that can help better secure your kid’s device, depending on their needs. We've broken them down into four categories: Parental Monitoring, Security, Safety, and Privacy.

Note: If you do not see these settings in your Android device, it may be out of date or a heavily modified Android distribution. This is based on Android 14’s features.

Parental Monitoring

Google has a free app for parental controls called Family Link, which gives you tools to establish screen time limits, app installs, and more. There’s no need to install a third-party application. Family Link sometimes comes pre-installed with some devices marketed for children, but it is also available in the Google Play store for installation. This is helpful given that some third-party parental safety apps have been caught in the act of selling children’s data and involved in major data leaks. Also, having a discussion with your child about these controls can possibly provide something that technology can’t provide: trust and understanding.

Security

There are a few basic security steps you can take on both your own Google account and your child’s device to improve their security.

• If you control your child's Google account with your own, you should lock down your own account as best as possible. Setting up two-factor authentication is a simple thing you can do to avoid malicious access to your child’s account via yours.
• Encrypt their device with a passcode (if you have Android 6 or later).

Safety

You can also enable safety measures your child can use if they are traveling around with their device.

• Safety Check allows a device user to automatically reach out to established emergency contacts if they feel like they are in an unsafe situation. If they do not mark themselves “safe” after the safety check duration ends, emergency location sharing with emergency contacts will commence. The safety check reason and duration (up to 24 hours) is set by the device user. 
• Emergency SOS assists in triggering emergency actions like calling 911, sharing your location with your emergency contacts, and recording video.
• If the "Unknown tracker alerts" setting is enabled, a notification will trigger on the user's device if there is an unknown AirTag moving with them (this feature only works with AirTags currently, but Google says will expand to other trackers in the future). Bluetooth is required to be turned on for this feature to function properly.
  

Privacy

There are some configurations you can also input to deter tracking of your child’s activities online by ad networks and data brokers.

• Delete the device’s AD ID.
• Install an even more overall privacy preserving browser like Firefox, DuckDuckGo, or Brave. While Chrome is the default on Android and has decent security measures, they do not allow web extensions on their mobile browser. Preventing the use of helpful extensions like Privacy Badger to help prevent ad tracking.
  
• Review the privacy permissions on the device to ensure no apps are accessing important features like the camera, microphone, or location without your knowledge.

For more technically savvy parents, Pi-hole (a DNS software) is very useful to automatically block ad-related network requests. It blocked most shady requests on major ad lists from the malware we saw during our investigation on a kid’s tablet. The added benefit is you can configure many devices to one Pi-hole set up.

DuckDuckGo’s App Tracking protection is an alternative to using Pi-hole that doesn’t require as much technical overhead. However, since it looks at all network traffic coming from the device, it will ask to be set up as a VPN profile upon being enabled. Android forces any app that looks at traffic in this manner to be set up like a VPN and only allows one VPN connection at a time.

It can be a source of stress to set up a new device for your child. However, taking some time to set up privacy and security settings can help you and your child discuss technology from a more informed perspective for the both of you.

Today we are introducing Badger Swarm, a new tool for Privacy Badger that runs distributed Badger Sett scans in the cloud. Badger Swarm helps us continue updating and growing Privacy Badger’s tracker knowledge, as well as continue adding new ways of catching trackers. Thanks to continually expanding Badger Swarm-powered training, Privacy Badger comes packed with its largest blocklist yet.

We continue to update and grow Privacy Badger’s pre-trained list. Privacy Badger now comes with the largest blocklist yet, thanks to improved tracking detection and continually expanding training. Can you guess when we started using Badger Swarm?

Privacy Badger is defined by its automatic learning. As we write in the FAQ, Privacy Badger was born out of our desire for an extension that would automatically analyze and block any tracker that violated consent, and that would use algorithmic methods to decide what is and isn’t tracking. But when and where that learning happens has evolved over the years.

When we first created Privacy Badger, every Privacy Badger installation started with no tracker knowledge and learned to block trackers as you browsed. This meant that every Privacy Badger became stronger, smarter, and more bespoke over time. It also meant that all learning was siloed, and new Privacy Badgers didn’t block anything until they got to visit several websites. This made some people think their Privacy Badger extension wasn’t working.

In 2018, we rolled out Badger Sett, an automated training tool for Privacy Badger, to solve this problem. We run Badger Sett scans that use a real browser to visit the most popular sites on the web and produce Privacy Badger data. Thanks to Badger Sett, new Privacy Badgers knew to block the most common trackers from the start, which resolved confusion and improved privacy for new users.

In 2020, we updated Privacy Badger to no longer learn from your browsing by default, as local learning may make you more identifiable to websites. 1 In order to make this change, we expanded the scope of Badger Sett-powered remote learning. We then updated Privacy Badger to start receiving tracker list updates as part of extension updates. Training went from giving new installs a jump start to being the default source of Privacy Badger’s tracker knowledge.

Since Badger Sett automates a real browser, visiting a website takes a meaningful amount of time. That’s where Badger Swarm comes in. As the name suggests, Badger Swarm orchestrates a swarm of auto-driven Privacy Badgers to cover much more ground than a single badger could. On a more technical level, Badger Swarm converts a Badger Sett scan of X sites into N parallel Badger Sett scans of X/N sites. This makes medium scans complete as quickly as small scans, and large scans complete in a reasonable amount of time.

Badger Swarm also helps us produce new insights that lead to improved Privacy Badger protections. For example, Privacy Badger now blocks fingerprinters hosted by CDNs, a feature made possible by Badger Swarm-powered expanded scanning. 2

We are releasing Badger Swarm in hope of providing a helpful foundation to web researchers. Like Badger Sett, Badger Swarm is tailor-made for Privacy Badger. However, also like Badger Sett, we built Badger Swarm so it's simple to use and modify. To learn more about how Badger Swarm works, visit its repository on GitHub.

The world of online tracking isn't slowing down. The dangers caused by mass surveillance on the internet cannot be overstated. Privacy Badger continues to protect you from this pernicious industry, and thanks to Badger Swarm, Privacy Badger is stronger than ever.

To install Privacy Badger, visit privacybadger.org. Thank you for using Privacy Badger!

• 1. You may want to opt back in to local learning if you regularly browse less popular websites. To do so, visit your Badger’s options page and mark the checkbox for learning to block new trackers from your browsing.
• 2. As a compromise to avoid breaking websites, CDN domains are allowed to load without access to cookies. However, sometimes the same domain is used to serve both unobjectionable content and obnoxious fingerprinters that do not need cookies to track your browsing. Privacy Badger now blocks these fingerprinters.
