Our upcoming 2-factor fingerprint unlock will make using a strong passphrase as primary unlock method practical via fingerprint+PIN secondary unlock instead of fingerprint-only. Great for people who want to avoid relying on secure element throttling but don't want fp-only unlock.

GrapheneOS provides users with the ability to set a duress PIN/Password that will irreversibly wipe the device (along with any installed eSIMs) once entered anywhere where the device credentials are requested (on the lockscreen, along with any such prompt in the OS).

The wipe does not require a reboot and cannot be interrupted. It can be set up at Settings > Security > Duress Password in the owner profile. Both a duress PIN and password will need to be set to account for different profiles that may have different unlock methods.

Note that if the duress PIN/Password is the same as the actual unlock method, the actual unlock method always takes precedence, and therefore no wipe will occur.

    This is great, I would like to also see a duress fingerprint option.

        That’s funny. But I was thinking the opposite. Use your middle finger to unlock your phone, but your index finger is your duress finger. Because most people use their index finger/thumb. So it wouldn’t raise suspicion

          I would definitely accidentally wipe my phone haha

          I was kinda being facetious, more of an F U finger than a serious suggestion.

          In all honesty, I can’t see how this would be useful - either you’d have to use a finger that wouldn’t look natural, and give the game away, or use a thumb or index finger and constantly have to re-load your phone due to accidentally wiping it!

            If we get blessed with fingerprint readers on the back of the phone again, you could easily use inconspicuously any finger on your hand you want.

            Perhaps for a fingerprint duress mode it simply shuts the phone completely off requiring the password. That would be reasonable middle ground. It’d be annoying when you get it wrong, but after a couple minutes you could get your phone back

      Good reference, I would set it to something shorter like 12345 (same thing an idiot keeps on their luggage). Keep your pin yours, but if you set the duress code to a default PW like that (and dont have kids that would just try the it at random) if the phone gets taken there is a non-zero chance that they just guess it and nuke the device.

      Unexpected IT crowd reference.

      I think the android dialler has/had an Easter egg when you type this number in

      E: the AOSP one still has it :)
