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 Multi-factor authentication using Duo page for information on how to install and use Duo. (Please log on with your Cardinal Credentials when prompted.)
