If you get a new smartphone or mobile device, you’ll need to re-activate the Duo Mobile app in order for it to work on the new device. You can do this yourself by visiting the Duo Self Service link on the Connect To page, logging in and choosing “Device Options” next to the mobile device in "My Settings and Devices".
If you need more information please follow the instructions to Add, Edit or Delete a New or Existing Device
If you have any questions, don’t hesitate to contact the UMSO Help Desk for help.
