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.

The many negative comments speak the reality of this horrible service. I work for a major airline, and we are forced to use this app and constantly get locked out. The text notifications don't always work. You take too long to enter the verification code, and you get locked out. Customer service often puts you on hold and are rude. I do not recommend.

App used to work on my watch but now it doesn't. It pops up for me to log in or enter a code but it closes out when I try to approve or enter it. It force closes but then repeatedly pops back up. I have to log in from my phone because the watch app is not working. this is something that just started happening. it used to work without any issues. please fix.

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.
