Manage Devices: Reactivate Duo Mobile
Reactivation is needed when passcode and push generation do not work on a previously enrolled device.

Manage Devices: Resync Hardware Token
Hardware tokens can fall out of sync if the button gets pressed too many times. This will cause authentication attempts to fail. To fix this, you will need to generate 3 different distinct passcodes from your hardware token and try to log in with each of these distinct different passcodes. The system will notify you that the passcodes are invalid, even if you type them in correctly. After the fourth attempt, your token should resync itself and you should be able to log in normally
- Attempt to log-in to a CruzID Gold application again until you come across the following screen.
- Click on "Enter a Passcode". Then press the button on your hardware token once to generate a passcode.
- Enter this passcode into the text box on your computer. You will receive an error message that says " Incorrect passcode. Enter a passcode from a hardware token."
- Wait for your token to go blank. Repeat the previous two steps two more times.
- After the fourth correct attempt, the system should resync your token and let you log in.
