Managing OpenSearch users

One administrator user with the all_access role is automatically created for each cluster. A user with this role receives full access to the cluster — for example, they have the right to write data to all indices and in all tenants (tenants). The administrator can manage other cluster users via the OpenSearch dashboard and API. A list of OpenSearch operations available to the administrator can be viewed in the Supported operations.

The administrator username is admin. The administrator password is set when creating a cluster. After creation, the password cannot be viewed in the Control Panel, but it can be changed.

For more information about managing users and roles, see the Defining users and roles article in the OpenSearch documentation.
