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.
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.

User reviews
This is how all 2FA services should be. It sends you a ping asking whether to log in or not log in. Unlike other apps which send you a six digit pin and then you enter it. This allows you to instantly approve logins which is a more streamlined experience.
