Android power users who use the CyanogenMod custom ROMs on their Android phones will no longer have root access when installing the latest version of the ROM. The move has been made by the CyanogenMod team to make the Android platform more secure. Root access is a term used to indicate superuser access to the Android OS allowing the installation of apps that require access to parts of the OS that are normally placed off limits.
Superuser access and rights can still be enabled through an option in the Developer Options menu in the ROM. Root access can also be enabled selectively for either ABD, Apps only or for both. With superuser rights enabled by default any app can access the OS as well as all data stored on that device including private and sensitive stuff. The CyanogenMod team feels that with over one million devices running the ROM that it was too dangerous to ship the ROM with a security risk like root access enabled.
