Description

Kerberos is an authentication service that was originally developed at the Massachusetts Institute of Technology and is now used extensively around the world. Kerberos uses the NetID and NetID Password to validate a person's identity and permit access to services such as Bluestem, VPN, UIUC Dialup, UIUCnet Wireless, Active Directory, Software Webstore, and Walkup Computing. Kerberos is also used to change your NetID password, which you can do through the NetID Password Change form or by visiting the CITES Help Desk.

Who can use this service
  • Everyone at the Urbana-Champaign campus can use their NetID and NetID password to enter Kerberos-authenticated online applications (although individuals may not be authorized to actually use a particular application).
  • Individual departments can choose to implement Kerberos authentication on their web servers and for applications that they develop. For more information on how to do this, see the related Bluestem webpage.
