The Duo Mobile App

The Duo Mobile app is a free smartphone and tablet application that syncs with your USC 2FA account to complete the authentication process.

  • The app is required to use the Duo Push authentication method and can be used to provide offline authentication passcodes.
  • The app is not required to take advantage of the Call Me authentication method or to receive authentication passcodes via text message.

To download and install the Duo Mobile app on your device, visit your device’s application store and search for “Duo Mobile.” Look for the logo at the top of this page to make sure you are downloading the correct app.

The 2FA enrollment process will guide you through the process of connecting the app to your USC NetID account.
