System Account

A system account is a user account that is created by an operating system during installation and that is used for operating system defined purposes.

System accounts often have predefiend user ids. Examples of system accounts include the root account in Linux.

The distinction of system accounts and service accounts is sometimes blurred. Many system accounts run operating system processes, and in this respect resemble service accounts. Some system accounts, such as root, are also logged into by system administrators.

System accounts are generally privileged accounts.
