Duo Security Two-Factor Authentication

Two-factor authentication adds a second layer of security to your login in addition to your password. It requires you use something you have and something you know to log in. It’s much stronger than using just a password. The University uses Duo Security to provide this extra layer of security.

Methods for Logging in Using Duo

There are many ways to log in with Duo. We recommend that you set up multiple devices and methods. You may need a backup if the device or method you normally use is ever lost, damaged, or simply unavailable.
