Two-Factor Authentication

The university has implemented a two-factor authentication system to provide an additional level of security when using sensitive online services. Currently, the university is using a tool called Duo. Duo provides a user-friendly and secure two-factor authentication solution. With two-factor authentication, the regular UT EID login process is enhanced with an additional authentication step.
