@neilsardesai Weren't there some systems (I'm thinking Lotus Notes) where the masking for the password field was made of glyphs derived from the keys already pressed?

This was a sort of accessibility hint-- if you saw the *pattern* you were used to you know you didn't drop or double a keystroke, even if it didn't provide visibility for the raw data.

You could like sha256 the content of the field, then map the result onto a collection of emoji, for a similar effect.
