In the AFS Authentication application window, to obtain new tokens, click "Obtain new tokens"... your username will be formatted as one of two ways depending on if you have a Cornell NetID or Cornell GuestID:

• netids provisioned at CNF before Feburary 23, 2025 are: your_netid@CIT.CORNELL.EDU
  • We are in the process of migrating these netids to CORNELL.EDU ... if CIT.CORNELL.EDU no longer works, please try CORNELL.EDU
• guestids (and netids provisioned at CNF on or after February 23, 2025) are guestids and netids are both: your_guestid_or_netid@CORNELL.EDU

both are case sensitive... the part after the '@' symbol must be all caps. While your netid or guestid itself must be lowercase.

If you run into problems where the Windows AFS GUI throws an error and will not give you tokens, and you have verified you are using the correct username format and correct password, see the General - Windows AFS GUI Login Error section below.

Look for the Key icon at the top right of your screen and mouse over the icon. A popup will tell you when your credentials will expire (if renewable the credentials will be renewed). You can also right click on the key icon and choose "List Tickets"... look for the tickets labeled "afs/cnf.cornell.edu@CNF.CORNELL.EDU" . If the key icon has a yellow exclamation or a red x, then you should manually obtain new credentials. Simply left click on the key icon – you will be prompted for your password.
