Last week, the 9th Circuit Court of Appeals in California released a ruling that concluded state highway police were acting lawfully when they forcibly unlocked a suspect’s phone using their fingerprint.

You can turn that and Face ID off on iOS by mashing the power button 5 times- it locks everything down.

I’ve always wanted a setting to create a lockdown key and an unlock key. So something like middle-finger to unlock but index-finger to force it into PIN/password only mode. So you can have some convenience of a quick unlock but if an authority figure asks or forces you to unlock it you can one-tap lock it down.

That would be awesome.

In GrapheneOS, a single wrong fingerprint disables fingerprint unlock until the password is entered.

That’s not correct. It just says not recognized, and let’s you try again. I just tested it. Do you have documentation that it should work the way you said and mine is faulty?
