Duo Push

Duo Push is the easiest and quickest way of authenticating. You'll get a login request sent to your phone — just press Approve to authenticate.

If you get a login request that you weren't expecting, press Deny to reject the request. You’ll be given the ability to report it as fraudulent, or you can tap It was a mistake to deny the request without reporting it.

Duo Push and Notifications

You can respond to Duo Push requests from the Windows Phone lock screen or banner notification.

Swipe down on the Duo Mobile banner notification received when your screen is unlocked to approve or deny the request.

SMS Passcodes

You can authenticate using a passcode texted to your phone. To have Duo text you a passcode click the Text me new codes button after clicking Enter a Passcode.

The Duo Prompt's status bar indicates the passcode was sent to your phone. 

To authenticate using an SMS passcode, click the Enter a Passcode button, type in a passcode you received from Duo via text message, and click Log In.
