All of the files on a Linux system have permissions that allow or prevent others from viewing, modifying or executing them. The superuser "root" has the ability to access any file on the system. Each file has access restrictions, user restrictions, and an owner/group association.

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).

When you run an application that requires root privileges, sudo will ask you to input your normal user password. This ensures that rogue applications cannot damage your system, and serves as a reminder that you are about to perform administrative actions which require you to be careful!

Sudo will remember your password for a set amount of time (15 minutes by default). This feature was designed to allow users to perform multiple administrative tasks without being asked for a password each time.
