A thief flags you down, grabs your phone and makes you unlock it using your thumb.
A cop opens the cop car door, grabs your hand and unlocks your phone, or even easier, face unlock.
Granted, guns and torture are rather effective as well, but is anyone entirely against fingerprint unlocking?
Biometrics are fine as a /username/ but should not be used as a password - heard that on some security podcast ages ago and have kept with it since.
So basically I don’t use biometrics, lol
