What is the Celt Login Authentication System (CLAS) and Why Do I Have to Activate?
The Celt Login Authentication System (CLAS) allows users to login to a variety of online services
at UST including myStThom, Blackboard, Webmail, and off campus Library services with a single username
and password for all CLAS enabled systems. Your username is now referred to as your Celt Login ID.
Faculty and staff will also use your Celt Login ID to access the UST network and Outlook Web Access (OWA).
See the Celt Login Authentication System page for more information and help.
You are required to activate your Celt Login ID only once so that
you can create your new secure account profile. Once activated, you may use your Celt
Login ID and password to login to any UST online service where you see the CLAS logo.
If you have not yet activated your Celt Login ID and you are a current or returning user, please note that
your current user name and Celt Login ID will be identical; however, you are still required
to activate your Celt Login ID and choose a new password.
