What is a Multi-Domain (SAN) Certificate?
Multi-Domain Certificates, also called SAN certificates, offer complete control over the Subject Alternative Name field. These certificates are ideal for securing multiple names across different domains and subdomains (e.g., Exchange/OCS environments). You also have the option to add, change, and delete any of the SANs on the fly to reflect the evolving needs of your network.
With just one Multi-Domain (SAN) Certificate, you could secure the following domains:

Use Wildcards in a Multi-Domain Certificate
Security requirements vary greatly from network to network. As a result, you may require a Multi-Domain Certificate with Wildcard capabilities. We can accommodate this by making your SAN compatible with the asterisk (*) convention of Wildcards. This gives you more flexibility and simplifies management.

Loyal customer disappointment
Good service some employees need a bit of tech coaching
P.S. Turns out you dont have to provide passport data and phone bill. In my case i put my phone number in the index.html file of my IIS server running in my domain. That was good enough proof.
