Enroll in Duo

Trine University uses 2-Factor Authentication (2FA) to protect accounts and resources. This document provides instructions for enrolling your smartphone or tablet in Duo and contains some additional information you should know before enrolling.

What to know before you enroll:

If you have Trine email on your phone or tablet, delete the account from the device before enrolling in Duo. Once you are enrolled, re-add the account and approve the Duo request. After the account is re-added, you will be able to check your mail exactly the same way as before. The Duo approval must be approved once while setting up the account initially.

  • Android devices: Your email will not work in the native mail app on Android. You will need to install the Microsoft Outlook app if you wish to setup your email on your phone after enrolling in Duo.
