  • What about a "pin-prefix" before scrambling?

Having a scrambled PIN pad also indicates the possible existance of a Duress PIN,
which likely prevents the desired initiation of the task it was designed for.

IMHO a solution would be a prefix of say 2 or 3 or more digit's before the keypad becomes scrambled.
And at that point I guess it would be wise to monitor excessive (ab)use of the backspace key - and act on that.

    I can't see how. What makes you think that it indicates that?

      Since normal phones don't offer that by default, seeing such is a flag that the user took care about security.

      Or look at it the opposite approach: when there is an normal (unscrambled) PIN pad, I would deem the existance of a duress PIN less likely.

      Or in other words, I wish to not wake a sleeping dog, and have it look average and normal. Not special.

      And, there's a toggle for "Scramble PIN input layout" so you can turn this feature off. I just tried it from Settings > Security & Privacy > Device unlock > Fingerprint Unlock > Second factor PIN on my Pixel 7a running 2024123000. So if it can be turned off, does that not negate the entire ask?

      Put simply, if using a scrambled PIN layout would potentially get you into more trouble than it's worth in your country or specific life situation, then don't use a scrambled PIN layout. Am I missing something here?
