This topic describes the root user and other types of administrative users in AppDynamics.
The root user is a built-in Controller user with global administrator privileges in the Controller environment. Only the root user can access the System Administration Console, the web page where you can create and manage accounts in multi-tenant Controllers and configure global Controller settings in both single- or multi-tenant Controllers.
The root user can be thought of as a superuser for the Controller. Unlike other types of users, you cannot remove the root user account or create other superuser accounts in the Controller. The password for the root user is first set at installation time, but you can change it after installation by following the steps below.
While the root user has global administrative privileges, account administrators act as administrators only within individual accounts in a multi-tenant Controller. It's typically the role of the root user to create accounts and an initial administrator for the account, and the role of each account administrator to create additional users within the account.
For information, see Configure Roles and Configure Users.
You can change the root user password from the AppDynamics administration console page.
If you do not have the root user password for your installation and need to reset it, contact AppDynamics Support.
The Controller uses the built-in administrator account in the underlying Glassfish application server. To change the password for this user, you need to change it in two places, in Glassfish and in the password file used by the Controller, as follows.
The password change takes immediate effect.
