# System Admin
In order to facilitate the management of the TE system assigned by Root, the Root account can give any member in the system the role of "system admin" and specify the relevant system management permissions. System management permissions are divided into four modules: project management, system maintenance, member and access control, settings and upgrade, and can be selected separately. The entry is under "Member - System Admin".
Management permissions are divided into parent permissions and child permissions. When the parent permissions are checked, the member will be automatically given the child permissions of this type and also the future expansions that fall under the parent permissions. When new system management permissions arer added in later versions, Root will be notified of the change once Root enters the "system admin" page, and can perform permission checks. When "all" is checked, it includes all existing system management permissions, as well as extended permissions that can be granted in the future.
You can have at most 5 system admins by default.
