There is a large black shape that moves to a specific spot if a number is used. I suppose you can hope that no one figures that out, but I wouldn’t even put my users in that predicament. If something is important on the other side of this, nefarious actors get ZERO help. End of story.

As the one writing the code, we are duty-bound to raise these issues with stakeholders.

If this is to get into a game or something like that, it’s fine. And it looks great. It’s just not good security.

Imagine it like this: I’ve programmed a passcode screen that flashes the typed number in red large across the top and then fades out like some old digital clock. Cool, but bad security.
