When installing Automation 360, add OpenSearch credentials for enhanced security.

1. In the Provide Elasticsearch Credentials window, enter the credentials for OpenSearch in the Elasticsearch password field.
   Important: Ensure the following for your OpenSearch (Elasticsearch) authentication password:

   • Is alphanumeric that contains a minimum of 8 characters with one alphabetic letter in uppercase, one in lowercase, a number, and a special character.

     Use a unique and strong password (cannot be any of the commonly used passwords such as Admin@123, password , and so on) as a weak password is rejected by the OpenSearch library and the Control Room installation will fail.

   • The password cannot include a space, semicolon (;), percent (%), or backslash (\).
   • The first character cannot be a minus sign (-) or forward slash (\).
   This option is enabled only for the primary node of the cluster when you run the setup for the first time for an update or a new installation of the Control Room. When you enter the password, self-signed certificates are generated for encrypting the data traffic for inter-node and client communication.
   The option is disabled for subsequent installations because the password and certificates are retrieved and reused from the second node onwards.
   
2. Repeat the credentials in the Confirm Elasticsearch password field.
3. Select the Check only if installing on the first node of the backup Elasticsearch cluster check box when you want to install the Control Room on the primary node that will be used as a backup for the OpenSearch cluster.
   This option is available only if you have provided the OpenSearch credentials for the primary node during a previous installation. The option enables you to use the database backup that is created from the OpenSearch settings table after the primary node of the cluster is installed.
   The option is disabled for subsequent installations.
4. Click Next to configure the IP cluster.
