Password Guide

Remember the following principles when setting a password:

  • Protect your password.
    • Don't  write  down your password - memorize it.  In particular, don't write it down and leave it anywhere, and don't place it in an unencrypted file!
    • Use unrelated passwords for systems controlled by different organizations.
    • Don't give or share your password, even to someone claiming to be from computer support or a vendor.
    • Don't let anyone watch you enter your password. Don't enter your password to a computer you don't trust.
    • Use the password for a limited time and change it periodically.
  • Choose a hard-to-guess password.
    • The password setting interface will prevent you from choosing an insecure password. Even so, choose your password wisely.
    • Don't use something you'd find in a dictionary (in any language or jargon). Don't use a name (including that of a spouse, parent, child, pet, fantasy character, famous person, and location) or any variation of your personal or account name. Don't use accessible information about you (such as your phone number, license plate, or social security number) or your environment. Don't use a birthday or a simple pattern (such as backwards, followed by a digit, or preceded by a digit.
    • Instead, use a mixture of upper and lower case letters, as well as digits or punctuation. When choosing a new password, make sure it's unrelated to any previous password. Use long passwords. You might use a word pair with punctuation inserted, a phrase (an understandable sequence of words), or the first letter of each word in a phrase.
