You can use a smartphone for your authentication device. You can use a generated passcode or push notification, which lets you authenticate by just tapping a button. You can also receive your authentication passcode via an SMS text message, or receive an automated phone call that requires you to press any key to authenticate.

Authenticate on your smartphone
Up to four methods of authentication are available for smartphones: a Duo Mobile push notification, a Duo Mobile passcode, an SMS text message, or a phone call.
- Duo Mobile app - push notification (recommended) — a push notification is sent to the device, and you can review the request and tap Approve to authenticate. Internet or cellular access is required to use this method.
- Duo Mobile app - passcode — authenticate using a passcode generated with Duo Mobile. The app runs on your device so you don't have to have cellular or internet access to authenticate (as you do with push notifications).
- SMS text message — a text message with a seven-digit passcode is sent to your mobile phone.
- Phone call — you receive an automated phone call that requires you to press any key to authenticate.
