Sometimes abbreviated as PW and PWD, a password is a set of secret characters or words used to authenticate access to a digital system. Passwords help ensure that computers or data can only be accessed by those who have been granted the right to view or access them.

Strong password - Term used to describe a password that is an effective password that would be difficult to break. Often a strong password has between six and ten characters (the more the better), numbers, other characters, and both upper and lowercase characters. Below is an example of a strong password.
