How does multi-factor authentication work?

Multi-factor authentication (MFA) uses two levels of security to verify your identity:

• Level 1: something you know (that is, your username, passphrase, answer to a security question).
• Level 2: something you have (that is, your phone, tablet, hardware token).

At the University of Maryland (UMD), your Directory ID and passphrase serve as the first level of security. UMD uses Duo to provide the second level of security through your choice of various supported authentication methods.

This second level of security will require you to verify your identity through the Duo authentication prompt. To get started, view the steps in the First Time Enrollment in Multi-factor Authentication article. Contact the Service Desk for assistance with multi-factor authentication.
