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.
Note: If you change devices, you must register the new device.
Part one must be completed on a computer browser, and part two on a mobile device and on a computer browser.

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.
