= The Master Realm
When you boot {project_name} for the first time {project_name} creates a
pre-defined realm for you. This initial realm is the _master_ realm. It is the
highest level in the hierarchy of realms. Admin accounts in this realm have
permissions to view and manage any other realm created on the server instance.
When you define your initial admin account, you create an account in the
_master_ realm. Your initial login to the admin console will also be via the
_master_ realm.

We recommend that you do not use the _master_ realm to manage the users
and applications in your organization. Reserve use of the _master_ realm for
_super_ admins to create and manage the realms in your system. Following this
security model helps prevent accidental changes and follows the tradition
of permitting user accounts access to only those privileges and powers necessary
for the successful completion of their current task.

It is possible to disable the _master_ realm and define admin accounts within
each individual new realm you create. Each realm has its own dedicated Admin
Console that you can log into with local accounts. This guide talks more about
this in the <<_per_realm_admin_permissions, Dedicated Realm Admin Consoles>>
chapter.
