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.

For the latest Terms and Conditions see https://duo.com/legal/terms.

Nice and lean app. Though missing export functionality, doesn't feel being in control of own data.

Truly an awful app. Genuinely the most annoying, useless thing ever that only ever serves to make your life harder. Had to get a new phone? Good luck! The apps transfer feature doesn't actually work, and now you don't have access to ANYTHING you need for school! Definitely worth making sure nobody gets access to my homework in canvas.

Honestly it does what its supposed to I think, only open it to verify I'm signing in and thats all I need it to do. But there's an issue where I can't interact with anything on the screen, literally can't do anything so I'm stuck without access to my stuff because I can't press the button to verify my sign in. It doesn't happen every other time I use it but it happens often enough that its really frustrating. Edit: This bug has happened more often, hasn't been fixed Edit: Keeps getting worse
