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.

Ratings and reviews

One less star because of a minor usability thing which would make life easier for those us who need to type in codes into the app. The keyboard does not open up to the numpad or keyboard + number row at the top when clicking on Enter Code from a notification. Instead it opens to the default keyboard without the numbers requiring Pressing+Holding or manually switching to the keypad. Otherwise, it works well. I don't have issues receiving the appropriate notifications, either.

When it works, it works, but grudgingly. If you aren't running the most recent Android version, perhaps you have a slightly older phone, it will "remind" you to update, even if your phone is no longer getting android updates. Yes, thanks for reminding me I'm poor, duo. If you're not getting push notifications, you may need to disable battery optimizing for the app, or else android will stop the app from running in the background.

I've been extremely frustrated with the app for a few weeks now and finally got the point where I'm so sick of it I wanted to leave a review. Judging by the other top reviews here, I'm not the only one. I *still* keep accidentally denying my logins because they moved the 'Deny' button where the 'OK' button goes for pretty much every other app. There are other issues like notifications not showing up, but nothing is more frustrating to me when I'm still tired in the morning and deny my own login because this app swapped the buttons around.
