Celt Login ID Activation | University of St. Thomas Houston Texas

Celt Login ID Activation

The Celt Login Authentication System (CLAS) allows you to login to a variety of online services at UST including myStThom, Blackboard, Webmail, and Library services with a single username (your Celt Login ID) and password. Faculty and staff will also use it to access the UST network and Outlook Web App.

You are required to activate your Celt Login ID only once to create your new secure account profile. Once activated, use your Celt Login ID and password to login to any UST online service where you see the CLAS logo.

If you have already activated your account and are having trouble with your password, you may reset it here. If you continue to have trouble logging in, please contact the IT Helpdesk at ithelpdesk@stthom.edu or 713-525-6900.

To begin, please enter your UST ID number.
