PSA to iOS users: if you tap the lock button 5x it forces password-only unlocking. Useful at protests or any precarious situations with law enforcement.

Bringing up the shutdown screen (hold lock and either volume button) will also do it.

I did not know that. That is extremely convenient. Thank you.

Great idea and implementation! If you are hesitant to install this for any reason, you can accomplish the same thing with this one liner:

  sudo bioutil -ws -u 0; sleep 1; sudo bioutil -ws -u 1
Edit: here's a shortcut to run the above and then lock your screen. You can give it a global keyboard shortcut in the Shortcuts app. https://www.icloud.com/shortcuts/9362945d839140dbbf987e5bce9...

Neat idea. I remember way back in the day, there was some question as to the legality of compelled unlocking of devices; IIRC, it’s been deemed legal to compel a fingerprint, but illegal (under the first amendment?) to compel entry of a password—IIRC, as long as that password hasn’t been written down anywhere. I gather this is written to that end primarily? Or is there some other goal as well?

I wrote this after the case of a Washington Post reporter, Hannah Natanson, was compelled to unlock her computer with her fingerprint. This resulted in access to her Desktop Signal on her computer, revealing sources and their conversations. https://www.yahoo.com/news/articles/washington-post-raid-pro... Edit: I've a lot more details about the legality and precedence on the apps landing page https://paniclock.github.i…

Cool, thank you.

On GrapheneOS (and maybe android generic?) this calls the emergency number, I just found out (with a 5 second timer to cancel this luckily)

Earlier quoted context omitted.

Tapping it 5 (6? 7? 20?) times works better while panicked, though.

Hook this to a lid angle below 30° trigger in https://lowtechguys.com/crank and you can easily make it run on a simple lowering of the lid

This still leaves your device in an AFU (after first unlock) state, with user data decrypted, and should not be treated as secure.

The only thing you can do (to protect your data from forensics, etc) is to return it to BFU by shutting it off.

This is great. I see many times "security advice" against biometrics replacing password unlock, but most of the time I am more worried about getting recorded by somebody/something while typing a password in the open than anything else. This makes it better for those other cases.

While it's true that the legality of law enforcement forcing passwords in unclear, courts can absolutely force you to enter a password even if it's not written down by holding you in contempt indefinitely.
