Celt Login Authentication System (CLAS)
 

 


What is the Celt Login Authentication System (CLAS)?

The Celt Login Authentication System (CLAS) allows users to login to a variety of online services at UST including myStThom, Blackboard, Webmail and many more services with a single username and password for all CLAS enabled systems. 

What is a Celt Login ID?

Your Celt Login ID is the username that University of St. Thomas students, faculty, staff and affiliates use to access most of the University’s technology systems including UST Webmail, myStThom, Blackboard and off campus Library services. Faculty and staff will also use your Celt Login ID to access the UST network and Outlook Web Access (OWA).

For current and returning users, please note that your username is now referred to as your Celt Login ID.  You will still be required to activate your Celt Login ID and choose a new password.

How will it affect me?

You are required to activate your Celt Login ID  only once so that you can create your new secure account profile.

Remember to update all mobile and home devices that connect to UST online services with your new password – for example, if you use your mobile phone to check your UST email and/or calendar.

After activating your Celt Login ID once, you will simply use your Celt Login ID and password to login to any UST online service that displays the Celt Login Authentication System (CLAS) logo as pictured above.
