Protecting your Kerberos password

Your Kerberos password is very powerful-- it can be used to access many services. For that reason, it is essential that you protect it carefully.

  • Make it complex. The minimum length is eight characters; longer is better. Use a mix of letters (upper and lower case), numbers, and punctuation.
  • Don't share it! Don't ever give your Kerberos password to anyone. IT will never ask you to reveal your password via e-mail or the phone.
  • Don't use the same password anywhere else.
  • Be sure to log out of public omputers when you are done (e.g. the IRCs, library, internet cafe computers, etc.). This removes your credentials.
