One-Tap Authentication

Easy, Mobile Two-Factor Authentication

Convenient One-Tap Authentication

For the fastest and most secure login, use Duo’s mobile app to send push notifications to your phone as your second factor. Here’s how it works:

  • Enter your username and password into your login page.
  • Choose ‘Duo Push’ as your second factor on the next screen prompt.
  • Then, tap ‘Approve’ on the push notification sent to your phone.

Duo Push is an out-of-band authentication method that prevents remote attackers from stealing your password and your second factor. Learn about How Two-Factor Authentication Works.

If users prefer a different method, they can choose to answer a phone call, type in a passcode or use tokens. Authenticate wherever you are, with multiple devices. See our other Authentication Methods.
