“Why can’t I unlock my machine?”
Because I’m typing the password I used previously (Stage IV-ing it) and hitting enter before remembering it was changed
Remembering that you changed your password before you start typing, but having to pause for a second to remember what you changed it to
“I will unlock this machine after I have a cup of coffee.”
Knowing what the new password is immediately, but fingers haven’t yet developed the muscle memory to type it unconsciously
Sit down at the keyboard, and your ‘puter is magically unlocked as your fingers touch the keyboard. Soon after you reach Stage IV you will receive a notification that it’s time to change your password.
*All bets are off if you use an algorithm to generate a password for a system that requires actual strong passwords and two-factor authentication so that you don’t have to change it constantly.
