MFA-Duo - Removing Old Devices
This document will explain how to remove devices you no longer have possession of from Duo MFA.
When you no longer are in possession of a device, you should remove it from your authorized login devices to prevent another person from requesting a phone number from a phone company that may be your old phone number.
Steps to remove a device
Go to mynetid.wisc.edu/duo-portal and login using your NetID and password, then authenticate (confirm your identity) using your smart device or token/fob.
Note: 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.
For the device you would like to remove, select Device Options.
Select the red trash can icon.
Confirm that you are intentionally removing the device by selecting Remove on the confirmation dialog.
