After booting if the user enters the wrong encryption password the first and the second time they have the possibility to enter it again the third time.
If the third time the password is still incorrect there is no indication for that.
What makes things even more confusing is that there is a spinner identical to the one shown after the correct password is provided (and that is displayed until the user login).
So this spinner spins forever if the password is wrong the third time.
The user can hit the Escape key and see that the password was wrong but otherwise there is no indication. It seems the only is thing left to do is to reboot the computer.
