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.

Duo Push Request on Android

If you are running Android 4.1 or later, you can approve the request right from the notification.

Duo Mobile Notification

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.


Fingerprint Verification

Duo Mobile 3.10 and up also supports fingerprint verification for Duo Push-based logins as an additional layer of security to verify your user identity. If you're using a device with Android v5.0 or later and a fingerprint reader you'll need to scan your finger each time you authenticate via Duo Mobile (if required by your administrator).

Duo Mobile Fingerprint Prompt

If you're not able to scan your fingerprint using the sensor you can also approve the Duo authentication request using the device's passcode (the same one you use on the Android lock screen).


Passcodes

Just tap the key icon to get a one-time passcode for login. This works anywhere, even in places where you don't have an internet connection or can't get cell service.

Pull to Refresh

Check for authentication requests by pulling the account list down. Duo Mobile automatically checks for authentication requests, but if you think you have missed a request, then tap the list of accounts and pull down to refresh.


Backup & Restore

If your administrator enabled Duo Mobile's backup and restore functionality and you previously backed up your Duo Mobile accounts from the app to Google Drive you can restore your accounts to Duo Mobile on a new Android device via the guided recovery process. See the full Duo Restore guide here.


Troubleshooting

If you're not receiving Duo Push notifications, first try a pull-to-refresh. If this doesn't fix it, see the Duo Knowledge Base for additional Android troubleshooting steps.
