Being able to change your password is a basic skill you must master before you start using Unix. Whenever you change your password, you should immediately test to make sure it works properly. Use passwd to change your password to dontBL8 (“Don’t be late”). Log out and back in again to make sure it works. Then change your password back to what it was originally. Test again to make sure it worked.
