Duo (MFA): Manage Your Devices


The following article provides instructions for users who have already enrolled at least one device in Duo Multifactor Authentication (MFA) and wish to manage (add, rename, replace, or remove) any of their devices.

  • If you never had a device enrolled before, please go to First Device Enrollment article for further instructions.
  • If you have more than one user account (e.g. student AND student employee... or, staff AND student) and you want to enroll the same mobile device for both accounts, you will need to contact the ITS Help Desk to get assistance.

This article is divided into different sections. Please click on the desired link to jump to that section:

Recommended steps when changing or upgrading your phone or tablet:
If you are changing or replacing your existing mobile device (phone or tablet) in the Duo self-enrollment portal, we recommend that you first add the new device and enroll it in Duo MFA. Then, you can remove the old device. It is important to note that even phones that had their cellular service removed can still continue to generate the Duo passcode necessary to access the Duo enrollment portal. This helps to ensure that the user can still access the portal and manage their devices on their own.

For further assistance to obtain technical assistance from an ITS representative, please use the following means:
