When you install Informatica services, the installer creates the default administrator with a user name and password you provide. You can use the default administrator account to initially log in to the Administrator tool.

The default administrator has administrator permissions and privileges on the domain and all application services.

The default administrator can perform the following tasks:

Create, configure, and manage all objects in the domain, including nodes, application services, and administrator and user accounts.
Configure and manage all objects and user accounts created by other domain administrators and application client administrators.
Log in to any application client.

You cannot disable or modify the user name or privileges of the default administrator. You can change the default administrator password.
