Catholic University uses multi-factor authentication (MFA) to enhance the security of its systems. With multi-factor authentication, you use two of three "factors" to log into a University system:
- something you know (like a password or PIN), and
- something you have (like a smartphone), or
- something you are (like your fingerprint or face).
Duo is a software tool provided by Duo Security, a cloud-based access security provider. Duo enables multi-factor authentication for certain University systems and services.
Please view our Using Duo page for information on how to install and use Duo. (Please log on with your Cardinal Credentials when prompted.)
