A password is a form of secret authentication data that is used to control access to a computing resource. The password is kept secret from those not allowed access, and those wishing to gain access are tested on whether or not they know the password and are granted or denied access accordingly.

Unfortunately, we tend to reveal ourselves in our passwords. We often choose the name or birth date of a loved one; we use our address, telephone number, or even our banking PIN; we use the name of a favourite pop-star, actor, or football team. There are people who are wise enough to avoid any personal references but will choose a word that is too short, a dictionary word, a name or word spelled backward.

Should someone else guess or steal your password, they can masquerade as you, which means they would then have access to your files, your e-mail, your funds, confidential information and much more. They could modify or destroy your files, send threatening or offensive emails in your name, or subscribe to unwanted services for which you'd have to pay. For these reasons, the security of your passwords is one of the most important cornerstones of information security. It can't be over emphasised.
