About Duo Mobile
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.
