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
   If you have a new phone but the number is the same, you can try using the 'text me a code' option.
4. Click the gear to the right of your device, then click Reactivate Duo Mobile. 
5. Follow the prompts.
