Changing Your AFS Password


You can change your password from any system that has the Kerberos tools or AFS client installed. The easiest way for Linux users is to login to Polaris, Andes or Discovery and use the command rcpasswd. Here is an example of what that will look like.

legacy accounts:

Changing password for 'username' in cell ''.
Old password:                       (nothing echoes)
New password (RETURN to abort):     (nothing echoes)

or, recent accounts in RSTOR Kerberos system:

Changing password in K5 realm RSTOR. Enter old password first (Input is NOT VISIBLE)
Password for [email protected]:

Choose a good password. Password must be 10 characters minimum, and contain both lower and uppercase letters as well as numbers and/or non-alphabetic characters. Avoid words found in the dictionary.

On Mac or Windows systems, you need to open a terminal window and use either:

 kpasswd <afs-username>  (recent accounts)


kapasswd <afs-username> or kpasswd.afs <afs-username> (legacy accounts)

If you aren't sure which system you are in, try kpasswd first.  If it gives a 'No such user' or 'Client not found in Kerberos database', then try the legacy tools.  The Linux rcpasswd script takes care of figuring out which authentication system you are in.

Windows systems with Network Identity Manager can also use a Change Password icon within that tool.
