Duo Mobile on Android
Install Duo Mobile
Find the latest version of Duo Mobile in Google Play.
Supported Platforms: The current version of Duo Mobile supports Android 10 and greater.
Duo does not provide official support for non-standard custom Android distributions like OnePlus, LineageOS, or ColorOS, nor is Duo Mobile supported for use on ChromeOS.
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.
Activate Duo Mobile for the First Time
When you enroll in Duo for the first time and choose to add an Android device or use Duo Push, you're shown a QR code to scan with the Duo Mobile app to complete activation.
Launch Duo Mobile and tap Set up account.
To proceed with adding your initial Duo account to Duo Mobile, tap Use a QR code.
Use your camera to scan the QR code shown by Duo Enrollment in your browser. If you're prompted to allow Duo Mobile permission to take pictures and record video, please grant it.
Give the new account a name to complete adding it to Duo Mobile.
It's a good idea to take a few minutes to practice approving and denying Duo authentication requests if you haven't used Duo before. Tap Practice now to go through some training screens like this one. If you feel comfortable using Duo Mobile to log in to applications you can tap Skip.
You'll see your newly-added Duo account in the accounts list. Now you're able to respond to Duo Push authentication requests, or generate passcodes to log in to applications.
Duo Push
If you choose to authenticate with Duo Push, you'll get a login request sent to your phone — just press Approve to authenticate.
If you get a login request that you weren't expecting, press Deny to reject the request. You’ll be asked if this was a suspicious login. If you aren't trying to log into an application or service protected by Duo and don't recognize the request, tap Yes to notify your organization's Duo administrator. If you made a mistake or the login isn't suspicious, tap No to deny the request without reporting it.
Duo Push and Notifications
When the Duo Push notification shows up on your screen, tap where indicated to view the available actions: Approve or Deny.
Tap Approve in the notification to finish logging in to the Duo-protected application.
Tapping on the push request notification itself (instead of tapping the notification actions) takes you to the full Duo Push screen in Duo Mobile.
If your phone is running Android 13 or later, you may need to enable Duo Push notifications.
To enable Duo Push notifications:
- Press and hold on the Duo Mobile app icon and then select App info. On the following Duo Mobile app information screen, tap Notifications. Toggle All Duo Mobile notifications to on.
Fingerprint Verification
Duo Mobile 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 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).
Duo Mobile Appearance
Adaptive View
The accounts list in Duo Mobile adapts to you. If you rotate your device into a landscape view, your Duo Mobile accounts list rotates as well.
The individual accounts shown in the list change appearance as well, showing the full account information when you just have a few accounts, and switching to a minimized account view when you have many accounts to minimize scrolling in the app.
Dark Theme
Duo Mobile's dark theme depends on your Android system settings. There is no in-app toggle to enable dark theme. If your device has the system-wide dark setting enabled, Duo Mobile automatically switches to dark theme.
You can enable dark theme on Android in a few different ways:
- Go to Settings → Display → Theme and select Dark Theme.
- Pull down the Android settings from the notification tray and tap Dark Theme.
