Duo Mobile on Android
The Duo Mobile application makes it easy to authenticate — just tap “Approve” on the login request sent to your Android device. You can also quickly generate login passcodes, even without an internet connection or cell service.
Find the latest version of Duo Mobile in Google Play.
Supported Platforms: The current version of Duo Mobile supports Android 4.0 and greater.
To see which version of Duo Mobile is installed on your device, go to the Android Settings menu, tap Apps, then scroll down and tap Duo Mobile. The "App Info" screen shows the version.
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.
If you are running Android 4.1 or later, you can approve the request right from the 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.
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).
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).
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.
Adding Accounts to Duo Mobile
During the setup process you'll see a barcode to scan (it looks like this). Tap "Add Account" (or the plus button in the upper right). Scan the barcode to add the account to Duo Mobile.
If you ever need to re-add your account to Duo Mobile, contact your administrator.
Duo Mobile supports third-party TOTP accounts, like Google and Dropbox. Learn more »
Delete an account by long-pressing on an account. Then tap "Remove account" and confirm the deletion.
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
It is not currently possible to backup and restore your registered Duo Mobile accounts on Android.
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.
