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.

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.

I hate it so much. There is nothing I can't complain about that hasn't been said many times over. No idea why my university chose to use this authenticator when it's so unintuitive. I can't even approve my sign in requests because it always says "Cannot complete this request. If the problem persists, please contact your administrator" I did and nobody has ever seen this issue once. Something on your end or their end is messing up my ability to do assignments. Do better.

The app works great. What's knocking off a star is that I see you have an Apple Watch app on your website, and it would be great if you had a watch app on the Play Store as well. Also, for the most part, when signing in, the notification usually just shows up. However, sometimes it doesn't, and this is solved by just opening the app, and the accept/decline options come up.

My old phone was dropped and screen is broke and unusable. The app is set up in such a way you can't transfer to a new phone without the old. Looks like the developers didn't think this through. The app itself gives you no kind of option to put your work email in and wants to automatically search my Gmail which is not registered under for my account. Microsoft authenticator for my other client was so much easier to transfer. Duo needs to be better.
