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 on your iPhone, iPad, or Apple Watch.

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.

Works as advertised!


This app has served me perfectly for well over a year. Unlike the Google Authenticator app, this app backs up data to iCloud in a way that is tied to the device and cannot be recovered to another device. This is a huge time saver if you ever have to restore your phone and don’t want to reconfigure all your OTP entries. The UX works well and I’ve never had a problem with the generated codes. Highly recommended!

Solid 2FA 👍


Overall, 100% appreciate the straightforward layout. No extra nonsense - thank you!

I would love to have the ability to condense the row height. Duo is my goto 2FA, so naturally the scroll is getting rather long.

Thanks for your work!

Developer Response

Hi rad-livinski, thank you for the review. We will share your feedback with our development team.



For MFA time based codes this app is one of the best I’ve used so far. UI is very useable and easy to use and for the services that use Duo Push it’s even easier.
