MSSL Domain Validation Methods

MSSL Domain Validation Methods


This article provides step-by-step instructions for adding domains to existing MSSL accounts using Domain Validation Methods. This feature is available to all MSSL Customers. 

Overview of MSSL Domain Validation Methods

After initial Profile setup/vetting is completed, users can add additional domains to the profile and then perform domain validation. We offer 3 automated domain validation methods, allowing customers to add domains to MSSL profiles 24/7. 

MSSL Domain Validation Methods:

  • HTTP Based Validation Method - Ideal for customers that can upload a file to a specified directory under the ".well-known/" directory with a GlobalSign provided random string. 
  • DNS Based Validation Method - Ideal for customers that are able to create a DNS TXT record containing a GlobalSign provided random string for the domain. 
  • Approver Email Method - Ideal for customers that can receive an email sent to one of the predefined domain mailboxes (,,,, or or sent to one of the domain contacts listed in who-is.
