    Scan the barcode to enroll your mobile device in Duo multi-factor authentication
  7. Now, protect your account on all CAS login screens by enabling Enable Multi-Factor Everywhere with Duo Multi-Factor Authentication. After you turn on MFA Everywhere, you will be able to authenticate using Push notifications, passcodes, bypass codes or Call Back.
    NOTE: We recommend you Add another Multi-Factor Authentication Method or Device to your MFA Profile, and print Using Bypass Codes for Multi-Factor Authentication. This will prevent getting locked out of your account.
