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.

To begin, please enter your UST ID number.
