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.

Useless when reinstalling. I had to remove and reinstall it on my cell phone, but though it found my backup file it insists I'm using a new phone and requires me to "scan a QR code" from my "old phone" to receive access. It's the same phone, there is nothing to scan! It doesn't provide the option for the same phone! Nor can I access my workplace's IT support as Duo disabled that option! I'm unable to get into my work email to access time-sensitive material nor contact IT!

App was just average, no issues what so ever on my end. However, they removed the one tap feature, where when you try to login, all you have to do is tap accept. Now, you have to type in the security code every single time you try to login, which is frankly annoying. Why remove the one tap login feature, what made the app good just went away.

My old phone was dropped and screen is broke and unusable. The app is set up in such a way you can't transfer to a new phone without the old. Looks like the developers didn't think this through. The app itself gives you no kind of option to put your work email in and wants to automatically search my Gmail which is not registered under for my account. Microsoft authenticator for my other client was so much easier to transfer. Duo needs to be better.
