How to re-active your Duo Mobile app on existing and new device.
iOS
Android
Note: If you wish to restore the Duo Mobile App from one Android device to another, you must have the old device working as it will generate the QR code necessary to restore.
Any Dakota State University student/staff/faculty who needs to reactivate their Duo multi-factor authentication will need to either request the service, by clicking the link under "related services/offerings" on the right hand side of this page or call the support desk, 605-256-5675. ITS staff will verify personal information and an Duo reset link will be sent to the student's non-DSU alternative email address.
Within the email that was received, tap the Duo link to reactivate your Duo multi-factor authentication.
