How do I reactivate Duo Mobile?


This tutorial will walk you through how to reactivate Duo Mobile app on your mobile phone. Secure MFA is not eligible for reactivation unless you have another authentication method available to gain access to this dashboard.

If you are unsure, you can attempt to login to and if the Duo prompt does not present a phone call as an option, then you are most likely enrolled in Secure MFA. Contact the STC or your Local Support team if you have any questions or if you need to regain access without an alternate authentication method.
