Duo Mobile App - New Phone

For anyone that has Duo Mobile App setup on their smart phone and needs to replace their smart phone due to an upgrade or to replace one that was lost or damaged, please follow these quick steps to activate Duo Mobile App again.

The first step that needs to be taken is to download and install the Duo Mobile app on your new smart phone. You can find this in the Play Store (Google phones) or the App Store (iPhones) and it should look like this (and yes, it has a low rating).

If prompted, sign in with your NetID username and password. You should now be prompted to use Duo. Normally during this part of the Duo Authentication, selecting Send Me a Push would work, but with the new phone, this will not receive the push. Instead, click on Call Me and wait for the call (please note, this is only if you kept your same number for your new phone). Once you get the call, answer it, and push the # key on your phone to accept the Duo authentication.
