This article applies to: Two-Step Login

Log In Using the Duo Mobile App

Duo Push works with Duo Mobile, an app you install and activate on your smartphone or tablet. You can download Duo Mobile from your device’s app store.

Log In using Duo Push

  1. If you have most recently authenticated using Duo Push, the Open Duo Mobile screen should appear on your computer when you need to authenticate with Two-Step Login.

    If Duo prompts you for a different authetication method (for example, Answer the phone call) but you would prefer to use the Duo Push method, click Other options, then select Send Duo Push from the list of available methods.
  2. Open the Duo Mobile app on your smartphone or tablet.
  3. In the app, select Approve to authenticate.

  4. The service you were logging into will open on your computer or device.

Was this a suspicious authentication prompt?

Duo displays the app name and place of the login attempt. If you have not made a login attempt that required Two-Step Login, or if the information on the Duo Mobile screen doesn't match your current activity or location, then:

  1. Select Deny on the Duo Mobile app screen.
  2. When you deny a Duo request, the Duo Mobile app will ask, Was this a suspicious login?
  • Choose Yes if you suspect someone is trying to access your account.

Always report fraudulent attempts.
Selecting Yes will trigger an alert to the IT Security Office. A Cornell security engineer will check whether someone tried to improperly use your identity to access a Cornell app. This will help protect your sensitive personal information.
  • Choose No if you selected Deny by accident.

Your Location and Privacy

Duo does not track your exact location. It only records broad geographic data for the city or country where the login originated, such as Ithaca, NY. Duo only records a location at the time of the login attempt.
