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.

One star because of the pop-up error other reviewers have mentioned: "leads to a pop-up warning that one cannot respond without a WiFi or cellular Internet connection. That's ridiculous; I couldn't have received the push without an Internet connection." It is ridiculous. The error compounds when you try to click-in to react to the pop-up and the app kicks you out ot the homescreen.

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.

The app works fine but I can't get a feature fix that used to work. you used to be able to click approve from the notification that popped up when you signed in. now it gives an error message that you do not have. a mobile or Wi-Fi connection. when you open up the app, you can approve. please fix this bug so that you can approve a login from the notification that pops up instead of having to go into the app.
