Problems with Passwords There is a direct relationship between the ease with which a password can be remembered and the ease with which it can be guessed.

If a password is easy to remember, it is probably easy for someone else to guess.

If you think there is even a slight chance someone knows your password, change it. Don’t let someone see what you are entering as your password.
