DUO Push
If you choose to use a Smartphone as your authentication method for DUO, you’ll be able to authenticate with a tap of your finger using the DUO Push feature. After you’ve installed the DUO app and registered your device, you’ll receive a “push” notification on your phone or tablet each time you’re prompted to authenticate. To complete the authentication process, you’ll simply click the green arrow to confirm your identity and approve the login.
