The following guidelines are offered to assist in this area. Avoid Obvious Passwords - Don't use your name or obvious words such as computer, Macintosh, or Baylor as passwords. Ideally, real words should not be used as passwords. Use Long Passwords - Passwords on most systems must be at least six characters in length. Even if the system does not impose such a restriction, this is the recommended minimum length.
Longer passwords are even better as they are harder to guess by trial and error.
Don't Write Your Password Down - A written password is more easily discovered than one committed to memory. If you must write down a password, make sure that it is recorded in a secure location. Never leave a written password in places such as on the monitor or the underside of the keyboard where it is easily found. Frequently - If someone accidentally discovers your password, you may not be aware that it is being misused. When Typing a Password - Don't let someone look over your shoulder while typing your password.
