  2. Open the Duo Mobile app.
  3. In the app, select Approve to authenticate.

If you select Deny, you will see two options:

  • It seems fraudulent. Choose this option if you suspect someone is trying to access your account.
This will trigger an alert to the IT Security Office. A security engineer will look into whether someone tried to improperly use your identity to log in to a Cornell service.
  • It was a mistake. Choose this option if you selected deny by accident.

For details about installing and using the Duo Mobile app, go to Duo Security's Guide to Two-Factor Authentication and find your type of smartphone.
