Pro tip, if you suspect the police are going to take your phone, turn it off. As far as I am aware, finger print and face id do not work on initial startup and they can’t compel you to enter your pin without a warrant.
Better yet: don’t use biometrics. My phone has face recognition for unlocking, but I better stick to a PIN/PASSWORD.
Double check this in the state or country you’re in. I recall something from a few years ago where the police could force you to give a swipe pattern and maybe pin since these items are not covered in the same way that a password is.
Maybe in some countries but in a western one they aren’t getting a pattern or passcode unless you verbally give it to them. We do know though that there is some level of capability to crack phones though.
Indent to find an article to back up what I remember and in 2020, a woman was held in contempt of court and jailed for refusing to provide a passcode. The case was later overturned.
*counsel you. I’m picturing a police officer comforting a suspect who’s sobbing with a hand on their shoulder haha.
