The first user that accesses the QMC and adds the server license, obtains the role root administrator (RootAdmin) for the Qlik Sense system. This user has full access rights to all resources in the site: security rules, streams, nodes, and so on. Additional users can be assigned as RootAdmin if needed, or assigned other admin roles with other administrative rights.
Note: The root administrator cannot change or delete the security rules that are delivered with the Qlik Sense system. These security rules are listed in the Security rules overview page with Type set to Default.
