<human>:  What should I do if I am locked out of my computer?
<bot>: If you are locked out of your computer, the first thing you should do is try to remember any passwords you may have set. If you cannot remember them, you may have to reset your password. Alternatively, you could contact your system administrator if you have access to one. You may also be able to reset the lock on the system by booting in safe mode using a recovery disc or USB drive.
