About this app

Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Duo Mobile also has a companion app for Wear OS, Duo Wear, making secure authentication even more convenient on your smartwatch.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.

License agreements for third-party Open Source libraries used in Duo Mobile can be found at https://www.duosecurity.com/legal/open-source-licenses.

Doesn't always send push notifications, so I have to open the app. Other than that, great! Works well for authentication, and they recently added the ability to automatically transfer accounts to a new phone, which happened immediately and seamlessly for me :)

This app is impossible to restore even with restore turned on (I'm an early 2017 user who now needs to restore on a new device). The tech support team should in no way be titled "support" as they are unknowledgeable so the entire experience is frustrating. Authy app and Google authentication were super easy to transfer to my new device. Duo mobile is light years behind the competition imo.

After the last update, every authentication push notification fails with an error message in the app that there is no internet connection available. Then it requires opening the app directly and responding manually to the request each time. This used to never happen. Appears to only be happening for Pixel Phones?
