If you leave your fingerprints on the murder weapon, are you self-incriminating when they link you to the crime? Seems biometrics are just a bad idea when used exclusively for security. Supposed to be at least two of the following:
- something you know (password)
- something you are (biometric)
- something you have (usb key, key card, secureId app on your phone)
Funny how this isn't normally available for your phone. Any phones require a pin and a fingerprint? Or a fingerprint and a nearby bluetooth device?
You can add an app to give a second unlock method. There's a FOSS one called AppLock available on F-Droid to add a pattern. It works fine
