    Truecrypt had a false volume for this very purpose.

    You have one password to unlock your drive, and one password to fake unlock your drive and instead unlock a volume that looks like your drive, where you store stuff that looks important but isn’t your real secret.

      By physical here, they mean using your biometrics by force. They’re still not allowed to beat you with a rubber hose.

      A court, however, can force you to give up a password or hold you in contempt (which is essentially the rubber hose option). Having false unlocks defeats that

    iPhone users:

    • DO NOT USE FINGERPRINT unless you absolutely have to for, say, disability reasons.

    • if you use facial recognition, don’t. Same as above.

    • If you find yourselves in a situation with the police, tap the lock button 5 times. This forces a passcode to open the phone and they cannot (yet) force you to enter a passcode.

    Anytime I am filming a protest or anywhere near police, I just tap the lock button a bunch of times in my pocket and I can rest easy.

      Samsung users (not sure if it also applies to other android flavors):

      Go to settings>lock screen>secure lock>show lockdown option and turn it on.

      Now if you hold the power button for over a second, a menu pops up with an option to turn on lockdown mode. This disables all biometric unlock methods until the next time you unlock it.

    Wasn’t there a court ruling that forcing someone to unlock their phone was unconstitutional? The fourth amendment seems to indicate a warrent at least is required to search someone’s papers, in the modern era that should apply to phones, obviously the constitution is meaningless if they want to do whatever but still.

    Edit: in Riley v. California (2014) the Supreme Court unanimously decided that warrentless search of a cellphone during an arrest was unconstitutional.

      The laws vary from state to state, and I am not a lawyer. But in general, I think it works like this. Things like your fingerprints, face, retina, etc, identify you. In many states, if the cops ask for your identification you are required to give it to them, and they are allowed to force the issue. Things like passwords, access to the interior of your home or vehicle, access to your business files, and things like that are not your identity and normally require a judge to sign a warrant (unless there are “extenuating circumstances”).

      Personally, I think the forcing you to unlock your phone without a warrant is bullshit, especially since they have the upper hand anyway. And the phone isn’t going anywhere and neither are you. In most cases they have plenty of time to get a warrant.

        This is why everyone should go into their phone settings and enable the lockdown mode option if it’s avaialbe. When I get pulled over I hold the power button and choose lockdown mode and then the only thing that will unlock the phone is my password. But my camera still works.

        If your phone doesn’t have the option, just restart your phone. There’s a reason phones require the password and not biometrics on startup.

        There are two related but distinct issues, and I hope to keep them separate otherwise the conversation goes in circles:

        1 - Can police under the circumstances look at the contents of the phone at all? This is to say, if the phone is completely unlocked, can they look through it?

        2 - If the police are allowed to look at the contents, but the phone is locked, in what ways can the police unlock it?

        Subject 1: This is by far the more important question, and the one that seems to get ignored in discussions of phone searches like this. I would argue that under most circumstances there is no probable cause to search a phone- the phone can not contain drugs or weapons or other contraband, so to me this is the larger hurdle for police. Police should have to justify what illegal thing they think is on the phone that gives them probable cause, and I don’t think that pictures of illegal things are the same as the illegal things themselves. Lawyers would have to hash this out, because I do notice the suspect here was on parole so perhaps there is a clause of parole for this or something. But this is the bigger, much bigger issue- can police even look at the contents? There is an argument from the pro-search side that constants of an unlocked phone are in plain view, and so that right there is a big nexus for the issue.

        Subject 2: If we assume yes, only then does subject 2 become an issue. How much can police compel? Well, they can’t compel speech. A passcode would count as protected speech, so they can’t compel that. Biometrics however, from what I have seen of court reasoning, tend to be viewed as something a person has rather than something they know. This would be analogue to a locked container with a combination lock compared to a key. The police can not compel the combo, but if they find they key in your pocket they can take it and use it.


        If you are up in arms about privacy, my view is not to fall into the trap of focusing on 2 and the finer mechanics of where the line for what kinds of ways to lock a phone are, and focus on subject 1. Reduce the circumstances in which searching a phone is acceptable, even if the phone is unlocked to begin with.

          Yes, and it may be a good idea to have it just in case. But the courts in the US so far mostly ruled that police forcing you to give biometrics to unlock is fine, as it is the same as fingerprinting you when you are arrested. But forcing you to give pin/password is the same as testifying against yourself, which is against the 5th amendment. So they usually can’t make you to give them a pin/password. At least in theory. Still better to have it in practice.

          That’s law in the UK:

          Section 49 of the Regulation of Investigatory Powers Act 2000 gives the police the power to issue a notice which requires the suspect to disclose their PIN or password if necessary. You are not compelled to provide your password to the police in any instance.

          However, section 53 of RIPA makes it a criminal offence not to comply with the terms of a s.49 notice which is punishable by up to two years imprisonment and up to 5 years imprisonment in cases involving national security and child indecency.

      No matter how desperate companies want you to… Apple , looking at you

      Are you implying there is some ulterior motive in phone manufacturers including fingerprint scanners? That Apple has them because they secretly want to make it easier for police to conduct phone searches? Because that’s a very bold claim, and “because customers like the convenience” seems to me like a much simpler explanation.

        From experience, with facial scan or fingerprint scan available on Apple, 3rd party app require it. E.g. okta MFA login, for those with apple phones, using face scan can be forced. I know you are free to decline and free to quit the company requiring it, but just like any new data set, you soon won’t be able to live without providing it.

        Remember when a social security number was introduced, gov promised it wouldn’t be used as a identification number for any other purpose . Forward 50 years and now you can’t do anything without it.

    face based and fingerprint based unlocking schemes is a bad idea.

    if you dead someone can still unlock your phone with your corpse
