Solution: First, double-check your UST Login ID (it's the part before '@stthom.edu' in your email) and password for typos. If this is your first time logging into any UST system, you'll need to visit Microsoft 365 to set your password and security questions initially. Try clearing your browser's cache and cookies, or use a different web browser.

⚠️ Multi-Factor Authentication (MFA) Issues

Cause: Problems with your registered MFA device or setup.

Solution: If you are unable to complete MFA setup or no longer have access to your registered device, please contact the Tech Desk. They can assist with identity verification and help you re-establish your MFA settings.

⚠️ Account Already Claimed Error

Cause: You have either already activated your account or had a previous account reactivated.

Solution: If you know your username and password, try logging into OneStThomas directly. If you don't know your credentials, the Tech Desk can help verify your identity and provide account information.
