Used to work at a pretty secure place. Each button had a small screen on it, and the numbers were randomized. So apparently this is an actual concern.

Scramble pads. We have them where I work. Damn password can change a few times a week without warning. Gone for lunch? Well good luck getting back in until reception comes back to tell you the new code.

Had this once at a retail store while paying. Entering PIN without muscle memory. .... Weird and almost made 3 errors which would have blocked my card.

Those also prevent observers from being able to learn the code by watching someone type it in from a distance.

That's smart, but probably frustrating as an authorized user.

iirc this is a GrapheneOS feature too

I've seen this on payment terminals too. It's real annoying when you're used to do the same motion all the time. But safer obviously.

I wonder if this is a problem for dyslexia?
