The root user in Linux is the user which has administrative access to your system. Normal users do not have this access for security reasons. Kubuntu does not enable the root user. Instead, administrative access is given to individual users, who may use the "sudo" application to perform administrative tasks. The first user account you created on your system during installation will, by default, have access to sudo <emphasis>s</emphasis>uper <emphasis>u</emphasis>ser <emphasis>do</emphasis>. You can restrict and enable sudo access to users with the <application>Users and Groups</application> application (review the <ulink type="help" url="help:/kubuntu/keeping-safe/">Keeping Safe</ulink> documentation for more information).
