Unintended? Consequences. It encourages weaker passwords, since you are not going to type in 14 of more characters by hand. I tried.

On campus, one service timed you out pretty quickly if you dawdled typing your password. I suggested that you should fail if you type it too fast, instead, to foil shotgun password typing bots, and give users more time for longer passwords.

That was before password managers.

It's hard to get everything right. After some rounds of white-hat password cracking, (the ones I got were so lame)I decided to modify the passwd command to crack passwords on the way in. Much faster with the plain text.

I have distrusted facial recignition since the Columbo episode (spoiler) in which Dabney Coleman sends someone elseout in his car with a face disguise to be deliberately snapped by a traffic camera for an alibi.

The photographically-aware detective notices that the light is wrong.

Thanks for "Helping us understand" via Columbo's timeless wisdom. ;-)

I'm in charge of IT for a 120 person org, anything that's a barrier to copying and pasting passwords just encourages simple password re-use, and the dreaded "laptop festooned with password Post-Its".
