Does the Relationship Between the Primary Domain Name and Additional Domain Name Have Any Impact on Domain Names?

If Domain Type is set to Multiple domains, you can associate one primary domain name and at least one additional domain names with the certificate when applying for a certificate. One additional domain name per line.

For example, if you purchase three domain names, set one domain name as the primary domain name and the other two as additional domain names.

• A primary domain and additional domains can be equally protected.
