Privacy

What a terrible decision. That's like saying if you have a house key they can search your house.

That's why passwords are safer in this situation. Cops can't compel you to reveal it.

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.

Luckily GrapheneOS has a duress passowrd feature. Very useful for these situatuons!

OP can you put the country in the title? Like [US] for example

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.

Laughs in Galaxy S8 where the fingerprint scanner only works if all planets are properly aligned which happens only once in 28 years.

This has been the law for a while, it's just that more Circuits are aligning. Don't use biometrics if you don't want LEO to be able to access your phone. A password is covered by 5A in some circuits and in others it's likely sufficient to just refuse or claim faulty memory due to the stress of the situation. Regardless of the location, the contents of the device are covered by 4A and you may succeed in getting a lot of whatever is found thrown out -- classic you can beat the rap, but you can't beat the ride.

And this is why you never, ever, EVER enable biometrics. EVER. Make a damn password or at least a very long PIN and enter that shit every time.

I've said it before that I'll say it again: Biometrics are a convenience to allow you or anyone else to unlock your phone quickly. Biometrics are NOT security.

DO NOT use biometrics to secure your phone unless you want anyone who has you and your phone to be able to unlock your phone without your permission.

Worth noting, with the caveat that how criminals are treated could eventually become how everyone is treated on the right slippery slope:

provisions of his parole required him to surrender any electronic devices and passcodes

The 9th circuit court judges really have no fucking clue about technology do they

PSA FOR IPHONE:

if you press volume up, then volume down, then hold the power button until the power slider comes on, then it will disable biometrics until next unlock

Biometrics are not secret and should not be used in place of passwords. They are identity like a user name. It's the same problem with orgs trying to use ssn as a security challenge, with all the beaches pretty much everyone's is already public knowledge.

I wish there was a way to require both biometrics and PIN. They're both insecure on their own, but together they're better. Like instant MFA for your unlock. I would enable that immediately, if it was available.

Edit: then a password / passphrase in case one of the other two stops working (as an emergency unlock).

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

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

This is why you ALWAYS use a pw/pin.

Do not use thumbprint Do not use facial recognition

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

Just use a passcode. Passwords can't be forced from you by police. Judges are a different thing.

iOS users can press and hold the power and volume up button until the emergency call screen appears, then release. You now have to enter your PIN / Password to unlock again and not use TouchID / FaceID. Good luck trying to get me to tell you the code.

Doesn't it boil down to like what you know is safe, what you are can be used?

Like they can't make you give passwords, but biometrics are vulnerable.

This is Graphene OS had a distress code you can enter that will wipe the phone.

I think this would be different for someone not on parole. So like if you're just speeding and get pulled over I believe they would be violating the law/Constitution if they forced your thumb against your phone.

But they probably do it anyway so good idea to follow the lock down above in this thread.

(Also don't use electronics to do crimes y'all.)
