The root user is a sort of “superuser” that can perform advanced system administrative tasks on your system. If you have a VPS or Dedicated Server plan you can use the root user to perform tasks that other users (such as your cPanel user) do not have the privilege of performing.

The root user is not a secret. The root user or “superuser” is present in every Linux or “Unix-like” operating system. If you would like more information about what you can do with the root user, you are best advised to read some of the material provided in the next section.

Thoughts on “Is My Root User Hidden?”
I have root access but cannot use su on the terminal. I also could not use it in an ssh window. I get a bash error. I can only seem to use it if I log in to ssh as root.
Hello and thanks for contacting us. You should be able to use it in the WebHost Manager (WHM) Terminal. Your ability to use it in cPanel terminal depends on WHM shell access settings.
