Passwords: Longer Is Stronger

Longer passwords are stronger and more effective in protecting your account. Try for at least 15 characters.  Other strategies for creating strong passwords include these:
  • Mix upper- and lowercase letters, rAndoMly.  
  • Replace 1 or 2 letters with numeric digits.  
  • Use a passphrase.
A passphrase is often easier to remember than a password.  You can combine ordinary words, provided they're random enough to foil simple guessing: dog + jib + nectarine = dogjibnectarine, 15 characters long.  Or take the first sentence of your favorite novel.  Once you mix the case and add a digit, your passphrase is very strong.  

Your password is like your toothbrush: change it periodically, and never share it.  See the ITS Safe Computing page for more information.
