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.

horrible app. 1st off, when you log in your computer you have to approve the sign in on your phone. that was frustrating at first because I kept forgetting that so I would have to dig in my purse to find my phone. now, after you approve on your phone, you have to enter the code thats provided THEN once you're in you have to wait for the code they send you an enter that. meanwhile, I can't get paid until I clock in after all these verifications. 🤬🤬 money lost

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.
