Passwords are one of the strongest keys to your privacy. We use passwords to access our voice mail, to make purchases with Interac, and to log on to the Internet and check our email. The safest place to store your password in your head. Never share your password with another person. Avoid the temptation to write your password down; and avoid the temptation to save your password into your computer. For even higher security, change your passwords on a regular basis.
