Allow users to recognize when someone tried to guess their password on the lock screen

[spotlesscoder]

Problem

When you leave your PC in a locked state but unattended it could be that some attacker might try to guess your password.
You might want to be aware of failed login attempts while you were away.

Proposal

The password field should have a red accent color after a login attempt failed for the user which must only be cleared when a successful login for that user is done.
This also allows you to recognize when someone tried to guess your password when you were away.
