Apple Watch & Duo Mobile
Duo supports login request approval and passcode generation from an Apple Watch.
Apple Watch support requires Duo Mobile 3.8 or later. To see which version of Duo Mobile is installed on your device, open Duo Mobile and tap the menu icon. The app version will be displayed in the bottom left corner.
You'll need to enable Apple Watch notifications for Duo Mobile. Open the Watch app on your phone, tap "My Watch", and scroll down then tap the entry for Duo. Enable "Show App on Apple Watch".
Duo Push
When you receive a two-factor push notification, you'll also see the notification on your paired Apple Watch if your phone is locked. Apple Watch’s Taptic Engine is a linear actuator inside the device that produces haptic feedback, meaning it literally taps you on the wrist whenever you receive an alert or notification. That means you’ll also feel a tap whenever a login request is sent via Duo Mobile, letting you quickly log in or deny the request.
You can approve the two-factor authentication login request or deny the login request without ever touching your phone.
You'll only see the Duo request on your watch when your phone is locked. Notifications won't go to your Apple Watch when your phone is unlocked.
Passcodes
You can also generate passcodes from the Duo Apple Watch app. Simply launch the app from the watch and tap an account to generate a passcode for that account.
