SuperSU

SuperSU is a software application used on Android devices to manage root access. Rooting an Android device gives users privileged control over various Android subsystems, allowing for deeper customization and modification than is typically available. SuperSU acts as a gatekeeper for these privileged operations, prompting the user to grant or deny root access to applications that request it. This provides a layer of security and control, preventing potentially harmful applications from gaining elevated permissions without the user's explicit consent.

The application was developed by "Chainfire," a well-known developer in the Android community. SuperSU is typically installed after a device has been rooted, often through custom recovery environments like ClockworkMod Recovery or TWRP. It offers a user interface to review and manage which applications have been granted or denied root access, along with options to revoke access if needed. Advanced users can also configure various settings related to how root requests are handled. SuperSU has been a popular choice for managing root access due to its reliability and feature set, though alternative solutions have emerged over time.
