DUO (Multi-Factor Authentication)

We use Duo MFA to protect your information on Trinity’s applications. Duo MFA uses a second source of validation, like a phone or tablet, to verify the user’s identity before granting access. DUO is an application available in the Apple Store or Google Play Store, and its one-time setup per validation device makes it simple and easy to use.

How to get help

  1. New Device

    • We have enabled the Duo Instant Restore (which requires a user to set it up on their device), allowing Mobile App settings to be backed up and restored on a new or replacement device.

    • Currently, there is no way to self-register a new or replacement device if Duo Instant Restore isn’t enabled, so if you need to set up a new device, please reach out to ITS to reset the account.


  1. Account Lockout

    • If a user locks out their Duo account (10 failed attempts), they will need to reach out to ITS to have the account reset.
