Administrator

The Administrator permission is the highest authority on the workspace.  This role is responsible for adding users to the workspace and modifying the settings.  The Administrator of a workspace can access, modify, create, and delete any and all content on the workspace.  No folder or page security can be set on a workspace to keep a user with Administrator permission from viewing it.

Because of this, Administrators will never show as an option to be selected in the folder or page security settings.  There is no method to block a user with Administrator permission on a workspace from accessing any content.

Do not give Administrator permission to any user that you do not want to have total access of the workspace, including the power to delete content, remove users, or delete the entire site itself.
