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.

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.

It’s not available on Android watches, but it is on the Apple Watch. Unlike 19 years ago, building an iOS app today isn't drastically different from building an Android app. With tools like Flutter or React Native, we now have cross-platform compatibility that makes it easier to develop for both systems simultaneously. If the developers haven't created it, it is because they clearly don't want it !

Works so far as a replacement for Google Authenticator, which screwed me over this month. I'm hesitant to use Duo's Google Drive backup (for aforementioned reasons) but it has allowed me to copy my codes into other devices, which is quite useful in case I lose one of them. Only reason why this gets 4 stars is that there is no app lock feature. Question to devs: any plans to add biometric or PIN/PW-based lock to the app so you have to authenticate yourself before accessing it?

Fine as long as you NEVER need to change devices. Which is obviously unrealistic. Easily the biggest flaw with this app is that they make it very difficult for you to use your account on a new device, the process is unnecessarily complicated. And if you're trying to switch from an iPhone to Android or vice versa - forget it! Per their own Support/Help section, it is currently impossible to transfer your DuoMobile account cross-platform, all u can do is delete your old account and start all over.
