What's new in Duo Mobile 4.28.2
From version 4.28.0:
We're always working to improve user experience in Duo Mobile. This update introduces various behind-the-scenes improvements and minor bug fixes to enhance your authentication experience.
About Duo Mobile 4.28.2
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 www.duosecurity.com/legal/open-source-licenses.
