Security - Enrolling in Duo and Managing your Devices

Two-factor authentication (a.k.a. multi-factor authentication or MFA) is required at UW-Platteville for all employees and students. Duo is the service the university licenses for two-factor authentication. This document contains instructions for enrolling and managing your devices in Duo from a computer. NOTE: Emeriti account holders may be required to use two-factor if they used two-factor while they were employed. Emeriti who did not use two-factor while employed will not be required to use it for their emeriti account.

ITS strongly recommends installing the Duo Mobile app on your smartphone. The app is:

  • Easy to read
  • Sends notices if someone tries to access your account
  • The fastest option compared to SMS text
