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.

Used to work but broken now. This app used to work like 5 years ago or so. It was very annoying because it popped up for literally everything connect to my accounts, so I felt like I had to log into every single page I visited. But it did work. Just now I tried to use it to add a new account, and the previous two are there and deactivated, but the app is frozen. I can install and uninstall it, and it will load the home page, but none of the buttons work, and I'm unable to use the app entirely.

This app is okay but the interface is busted. When the phone is unlocked, it usually allows a response to a push notification requesting 2FA approval directly from the notification drop-down. In its current state, approving the request thusly 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. Support is only available for the enterprise customer, not the end users.

I'm now required to use this by my company on my personal phone which I think is very intrusive. It seems like every time I use it, it turns off my ability to make a phone call. I've tried clearing the cache I've tried uninstalling and reinstalling. Very frustrating and the only thing that helps is to completely restart my phone each time I have to use this app, which with the way my company set it up, it's almost 10 or more times a day.
