    You can add your new phone by going to "My Settings and Devices" at the DUO prompt and following these instructions: https://guide.duo.com/add-device

    NOTE:  If you're adding a new device to replace one that you previously activated for Duo Push, don't select the Duo Push authentication method on this page unless you still have the original device. If you don't have the original device, but you have a new device with the same phone number, then you can authenticate with a phone call.
