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.

Now, the duo isn't working. He said I need to update my Duo apps. When I check the Play Store, there is no update. A few weeks later, I found out my Android phone was too old to run the apps, so I bought a new one. I log in using my old email. Now, even worse: all my account access is disabled. I click on reconnect, but nothing happens. Please Update your apps so I can log in using my old phone. Because it's still sending push notification every time I try to login

garbage token app that is only in use because of corporate marketing. unreliable, slow and constantly crashing. I waste more productivity trying to get the app to work than anything else.

annoying I'm trying to transfer Duo to another mobile. I try and scan the QR code but it says failed to add account. please make sure you're scanning the correct narcos and try again.. seriously your stupid app created the bar code. not helpful and there seems to be no contact information to try and resolve this.
