Duo Mobile is an essential application for anyone using two-factor authentication (2FA) to secure their online accounts. This guide will walk you through everything you need to know about installing and activating Duo Mobile on your Android device, with a special focus on Duo Mobile QR code setup, a quick and efficient method to get started.
Whether you’re new to Duo Mobile or looking to deepen your understanding of its features, this article provides a detailed walkthrough, ensuring you can confidently manage your account security.

Activating Duo Mobile with a QR Code: A Step-by-Step Guide
After installation, you need to activate Duo Mobile to link it to your Duo account. The most common and convenient method is using a QR code.

Initiate Duo Enrollment: When you enroll in Duo for the first time through your organization or a service requiring Duo authentication, and you choose to add an Android device, you will be presented with a QR code on your computer screen or enrollment interface.
-
Launch Duo Mobile and Begin Setup: Open the Duo Mobile app on your Android device. On the welcome screen, tap Set up account.

Select “Use a QR code”: To activate using a QR code, tap the Use a QR code option.

After these steps, your newly added Duo account will be visible in your accounts list within the Duo Mobile app. You are now ready to use Duo Push or generate passcodes for secure logins.
Understanding Duo Push
Duo Push is the recommended and most user-friendly authentication method. When you choose Duo Push, a login request is sent directly to your Android phone.
To authenticate, simply tap Approve on the notification.

Handling Unexpected Push Requests:
If you receive a Duo Push request that you didn’t initiate, it’s crucial to tap Deny. You will be asked if the login was suspicious.
- If you did not attempt to log in and don’t recognize the request, tap Yes to report it to your organization’s administrator.
- If it was a mistake or not suspicious, tap No to simply deny the request.
For suspicious login reports, Duo Mobile will temporarily silence notifications for 20 minutes to prevent further prompts. You can still approve a legitimate request by opening the Duo Mobile app directly.
Managing Duo Push Notifications
When a Duo Push notification appears, you can directly interact with it from your notification shade.
- Tap Approve or Deny directly from the notification to quickly respond to the request.
- Tapping the notification itself (instead of the action buttons) will open the full Duo Push screen within the Duo Mobile app.
Enabling Notifications (Android 13+):
If you are using Android 13 or later and are not receiving Duo Push notifications, you may need to manually enable them:
- Long-press the Duo Mobile app icon.
- Select App info.
- Tap Notifications.
- Toggle All Duo Mobile notifications to the “on” position.
Enhanced Security with Fingerprint Verification
For added security, Duo Mobile supports fingerprint verification for Duo Push logins on devices with fingerprint readers. If enabled by your organization, you may be required to scan your fingerprint to approve Duo Push requests. Alternatively, you can use your device passcode if fingerprint scanning is not possible.
Verified Duo Push: Adding an Extra Layer of Protection
Some organizations may implement Verified Duo Push, requiring you to enter a verification code displayed on the login screen into Duo Mobile when approving a request. This feature protects against accidental approvals and ensures you are actively verifying each login.

- When using Verified Duo Push, a six-digit code will appear on your login screen.
- Enter this code into the Duo Mobile app when you receive the push notification and tap Verify.
If you enter an incorrect code, you will be prompted to try again or choose another authentication method.
Streamlined Login with Bluetooth Autofill for Verified Duo Push
For an even smoother Verified Duo Push experience, Duo Mobile offers Bluetooth Autofill. If enabled by your organization and you have the required app versions (Duo Mobile 4.72.0+ on Android 12+ and Duo Desktop 6.13.0+), verification codes can be automatically filled in.

The first time you log in with Bluetooth Autofill enabled:
- Grant nearby devices permissions when prompted by tapping Continue and then Allow.
- Ensure Bluetooth is enabled on both your Android device and your computer.
Duo Mobile will then automatically detect the verification code from your computer via Bluetooth and autofill it in the app.
Proximity Verification: Ensuring Device Proximity for Authentication
Another security feature is Proximity Verification, which requires your mobile device to be near your computer during authentication. This also utilizes Bluetooth permissions and requires compatible Duo Mobile and Duo Desktop versions (Duo Mobile 4.81.0+ on Android 12+ and Duo Desktop 6.13.0+).
