I have a new mobile phone and now I cannot authenticate using Duo.

  1. Enter your username and password into myRedDragon.
    Note: If it automatically logs you in, it is remembering your device. Use a different browser or computer, or use an incognito/private tab to force a Duo auth.
  2. Before you authenticate, click the Settings button to the right of the SUNY Cortland logo.
  3. Click My Settings & Devices. Use your back-up authentication method to authenticate. 
    Note: If you do not have a backup device you will need to call the Technology Help Center at (607)-753-2500
  4. Click the gear to the right of your device, then click Reactivate Duo Mobile. 
  5. Follow the prompts.
