# Using &kde; as Root

For &UNIX; operating systems there are often different users, which in turn might have different privileges. The conventional method is to have an ordinary user account, whose files are generally stored in `/home/username`, and then to also have a `root` account. The `root`, or Super User, account has system-wide privileges, being able to modify any file on the system.

Although this means that it is easy to perform administrative tasks without hassle, it also means that there are no security restrictions imposed upon it. Thus, a small typographical error or other mistake can result in irrevocable damage.

Some of the operating systems that run &kde; come with a graphical `root` login enabled. Despite this, you should never log in to &kde; as `root`, and you should never need to. Your system is far more open to attack, particularly if you are browsing the Internet as `root`, and you dramatically increase your chances of damaging your system.

Some &Linux; distributions have tried to stress this point so much that they have disabled the `root` account altogether, and instead use the `sudo` model. Nevertheless, the basic security model in `sudo` is the same as `su`, and thus they share the same security strengths and weaknesses, essentially.

If you should ever need to run a program with Super User privileges, then it is always recommend that you use &kdesu;. From &konsole; or from hitting &Alt;F2, enter `kdesu `application``, and the application will be run with the appropriate Super User privileges.

Even if you have set up your system to use `sudo`, or you are on a distribution that uses `sudo`, such as &kubuntu;, you should still use &kdesu;. The program will be appropriately modified by the developers to use the correct settings. You should not, however, ever use `sudo `application`` to run an application with `root` permissions; it can derange permissions of certain configuration files for a program. Running a graphical applications as `root` in general is not a good idea, but using &kdesu; will always be your safest bet with it.
