The current version of Duo Mobile supports Android 10.0 and greater, as well as Android Go 10.0 and greater. Duo recommends upgrading to the most recent version of Android available for your device. We cannot ensure the compatibility of Duo Mobile with custom variants or distributions of Android. Duo Mobile is not supported for use on ChromeOS or Huawei. Duo does not provide official support for non-standard custom Android distributions like OnePlus, LineageOS, or ColorOS.
Android 9 and older
Users on Android versions 9 and older will not be able to download the latest version of Duo Mobile from the Play Store. This removal from the Play Store will not affect mobile app authentications for users who have already downloaded the app.
Additionally, we no longer provide troubleshooting support, bug fixes, maintenance fixes, or security updates for mobile devices running versions 9 and older.
This end-of-support milestone is not an end-of-life for our application on devices with this operating system (or older operating systems that are no longer supported); push and app-generated passcode authentications will continue to function on installed apps. While authentications will continue to function, we always recommend users run the latest version of Duo Mobile on a supported operating system to maintain a strong security posture and get access to the latest features and improvements.
As SMS-delivered passcodes and phone callback authentication do not rely on the Duo Mobile app, Duo will continue to support these types of authentication for older devices with or without the app.
