Duo: Reactivate Duo on your Smart Phone

This document provides instructions for reactivating Duo Mobile on your smart phone after you have switched smart phones, uninstalled the Duo Mobile application on your phone, or performed a factory reset. Follow these steps so you can receive Duo push notifications and will be able to generate one-time use passcodes.


To proceed, your smartphone will need to be able to receive calls or texts if it is the only device you've enrolled in Duo but it has to have the same number when it was first enrolled to receive a phone call or SMS text message.
