Duo Two-Factor Authentication

On March 27, 2024, W&M Information Technology will update Duo and the prompt you are used to seeing will have a new look. The new authentication experience is called the Duo Universal Prompt, and it’s designed to be even simpler and faster than ever. 

Duo is William & Mary's two-factor authentication service. It provides an additional level of security to prevent unauthorized access to a variety of systems.  Two-factor authentication helps protect against increasingly sophisticated security threats, like phishing, and thwarts unauthorized use of your login credentials. Duo - Two Factor Authentication

How it works

Duo, as a two-factor authentication system, has two distinct login steps.

Step 1)  Sign-in with your W&M Username and password.

Step 2) Confirm your login by entering a code sent to an enrolled device.

Find more details about how Duo works in the Duo Guide.
