How to Enroll in Duo

3) It's that easy — You're enrolled!

When Duo goes into effect for your account, you'll start seeing prompts to confirm your identity with your device when accessing protected services.

4) Register a backup device (optional)

  • We recommend registering at least two devices so that you have a backup method in case your main device is unavailable.
  • The registration instructions are the same as above, with one exception: After your first device has been registered, you'll be required to complete the Duo prompt to change your Duo settings
  • Don't have a second device? If you're using the Duo Mobile app, it has a built in backup! You can write down passcodes and use them later, even if your device doesn't have service or isn't available.
