Duo Mobile

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.

Ratings and reviews

Keep getting notice to update my version. But there's no option to do so in the app. And the Play Store doesn't have an option to update. Yay! Constant error messages that you've given me no solution for!! My ADHD brains loves wrestling with this issue everyday I login. Thanks!

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!

Good app, the one tap login feature should be added back so users can choose whether they want to use one tap or a 3 digit generated pin. Also, a suggestion I have for the developers is to make this app available on PCs so people can use their PC also as a verification option along with their smartphones.
