Duo Security Two-Factor Authentication

The University uses a two-factor authentication system for users who need access to its enterprise-level applications (e.g., CS PeopleSoft, EFS PeopleSoft, EDMS, and the Data Warehouse) and for the underlying servers and databases. A form of authentication stronger than just a password, two-factor authentication requires two factors to authenticate: something you have, and something you know.

What is Duo Security? 

In the past, two-factor authentication solutions have used hardware tokens (or “fobs”) that users needed to carry, but Duo Security’s two-factor authentication solution uses your mobile device to help verify your identity. This is a substantial improvement since your mobile device is something you already have, know how to use, and are likely to notice if it’s missing. If a mobile device isn’t available a landline phone can be used instead (hardware tokens are also available). Using a combination of your Internet Password and Duo Security helps prevent an attacker from accessing secure information, even if they know your password. 

Which Method is Right for Me?

There are a number of different methods for logging in. Use whichever method is most convenient for you. You can even enroll multiple devices and use multiple methods as a backup in case the device you normally use to log in is ever lost, damaged, or simply unavailable.
