In order to provide added protection to college data Thiel employs 2-factor or "multi-factor" authentication. In addition to using their username and password, under certain circumstances, users must also authenticate using a phone (second factor of authentication) in addition to their username and password (first factor of authentication). The advantage of adding a second factor of authentication is that in the event that a user's credentials (username/password) are compromised, that alone will be insufficient for someone to gain access to sensitive college data. They would also need to gain possession of the user's phone in order to make use of the compromised credentials. Thiel uses Azure MFA to provide this second factor of authentication and increase the protection of college data.

The guides below can be followed to setup and configure MFA for your account.

You can also setup MFA on your own personal accounts. Which the college recommends.
