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.

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.

Ditch the animated splash screen. Sure, it only takes a second to load, but when you have to use this app to unlock to your work computer, that one second is super annoying. If I just received a push notification to approve a login, why do I need to wait for you to tell me that I'm opening the Duo app? It was on the push. It's on the login page. Don't make the process longer than it needs to be.

This app is a point and tap nightmare. I have lost backups. I have lost recovery. I have lost sleep because of this app. It's beyond not being user friendly it's about as useless as putting a screen door on a submarine. Yeah it's "safe" because you cannot even get it to work when you switch to a new phone. This app it a good example of what not to use for your authenticator. Absolutely a freaking nightmare. Thanks duo for putting me in a state of dismay.

No cell/wifi bug. Everytime I get a push notification to unlock my computer, it says I have no cellular or Wi-Fi connection. Open the app, it displays the error, click ok, then the app closes. I have to reopen the app again and then accept the login push. Started doing this after the last update. Cleared cache and restarted phone, works once. Pixel 6 Pro
