Doesn't Android know when the user is authenticating? How many seconds a day are you inputting to the lock screen? Doesn't need to be for any time the keyboard

Doesn't Android know when the user is authenticating? How many seconds a day are you inputting to the lock screen? Doesn't need to be for any time the keyboard is open. (Of course, doing it semi randomly is also now necessary, to obscure user unlock times.)
As to weak info, you do it again and again, I'd say it's pretty good info.
- adrianmonk 7y agoIf you're only trying to solve the very narrow problem of entering a PIN to authenticate to the system, then sure. When you said "during keyboard input", I thought you were being more general, but I suppose you must have meant during keyboard input of the system PIN. I don't think that PIN is the only sensitive information that matters, though. Android supports a numeric keypad input mode for apps. If I'm entering my credit card number into some app (Lyft, Amazon Shopping, etc.), that seems pretty sensitive. Maybe more sensitive than the system PIN even, because if I know your system PIN, I can't necessarily do anything with it unless I have physical access to your device or you've re-used the same PIN elsewhere.
