Before You Start

  2. Make sure you have your username and password for the Apple App Store.

Download the App

To download the App, click the link below:

If you are unable to run the DUO app for some reason, such as your device is too old or your device is restricted from downloading apps, then use text message (SMS) or phone call methods.
