MFA-Duo - Removing Devices

This document will explain how to remove devices (smartphone, token/fob) you no longer have possession of from Duo MFA.


When you no longer are in possession of a device (smartphone or token) or no longer wish to have a device registered to your account, you should remove it from your authorized login devices. Only the user who has the device registered the their account can remove that device.

Steps to remove a device

  1. Go to and login using your NetID and password, then authenticate (confirm your identity) using your smart device or token/fob. If you no longer have access to your device, use the MFA Duo Temporary Passcode application to get a temporary passcode for log in. Then click the blue Manage MFA Preferences and Devices button.

    Note: You cannot remove a device if it is the only device registered to your account. Be sure to add a new device before deleting your old device. Once a device is deleted, it can no longer be used to approve Duo authentication requests. If you are unable to delete a device, please contact the DoIT Help Desk (608)264-4357.

  2. In the Device Management Portal, find the device you would like to remove and select Edit.
