Securely Access University Applications with Duo

Duo Multi-Factor Authentication helps protect your Catholic University account by requiring a second verification step when you sign in. Duo is used to access several University services, including Cardinal Students, Cardinal Faculty & Staff, Cardinal Financial, and the University VPN.

The recommended verification method is Duo Push through the Duo Mobile app.

Manage Your Duo Account

Use the Duo Self-Service Portal to manage the devices and authentication methods connected to your account.

In the portal, you can:

• Add a new phone or device

• Reactivate Duo Mobile if Duo Push stops working

• Change your default device or authentication method

• Remove an old device

• Enroll in Duo if prompted during sign-in
