Last updated on September 27, 2022

The Duo Multi-Factor Authentication (MFA) service provides secure access to all UW-Madison applications. Paired with the NetID login service, Duo MFA adds an extra layer of identity protection onto the NetID login. Users can verify their identity using the Duo app, or by using a passcode from a token or fob.


  • Ensure users are legitimate at every access attempt
  • Verify the trustworthiness of each device used to access UW applications
  • Limit and monitor sensitive information exposure
  • Secure permissions for every user in any context
  • Simple and secure interface for every login


  • A mobile device that supports the Duo app to receive push notifications
