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.

U2F is a great idea but needs to be implemented with some key things in mind. A person is the ultimate and only true trusted entity. Duo very poorly handles the eventuality of a phone breaking, being lost, new numbers. This can be partially avoided for 90% of cases if people always set up 2 devices at the same time, more the better. 3 devices would fix 95% of complaints problems. However there needs to be a way to transfer to another phone after-the-fact, the technology allows, not the app.

This has to be the most draining, time consumed, most frustrating app I've ever used. This is my first review on play store so I'm pretty upset of how this whole process takes you in and out and loop to loop to a dead end. I'm at the point of transferring schools because of the steps involved if you lose your device, update a phone number or access your account. It literally has no function in my opinion. It does the same functions as google 2 step verification.

We have been using it for a few years now and have experienced next to no issues. I administer it for our company and it works wonderfully online or offline. Switching to a new phone is easy by using the migrate function and if you get a new phone and forget that then have it call/text you instead. All the reviews about people being mad that they are forced to use it are dragging the scores down, overall it is a stable and capable app.
