Now you can use a single SSL certificate on multiple WordPress websites

WordPress Multisite (MU) is an excellent feature that allows you to run WordPress multiple domains with a single installation of WordPress on your server. Ever since the release of WordPress 3.0, Multisite (MU) has been a vital part of the WordPress core system. WordPress Multisite is the easiest and perhaps the only option if you have multiple sub-domains, or want to run your blogs, or have numerous subsites. The only thing to keep in mind is that all these sites and blogs must be hosted on the same hosting provider.

The Multisite feature proves to be of major help when it comes to enabling SSL certificates as well. With Multisite feature by your side, you no longer have to bother yourself with the monotonous process of installing SSL for each and every subsite. A single SSL certificate is all it takes. Once you enable an SSL certificate on WordPress multisite network, all the traffic is transmitted through encryption methodology. Thereby, securing the information transferred back and forth between your server and clients.

When it comes to the word ‘multisite’, it can mean three different things. They are:

  1. Multisite as in subdirectories
  2. Multisite as in sub-domains
  3. Multisite as in multiple domains

Let’s understand each in brief.

Multisite as in subdirectories

Simply speaking, a subdirectory is like a folder within a cabinet. The cabinet here is your website itself. They are mostly used to categorize the content of your website.


  • com/blog
  • com/about-us
  • com/contact-us

If you perceive these two as multisite and want to enable SSL on them using the multi-site feature, you can’t. Why? Because, once you install SSL on the main URL, all the subdirectories automatically transfer to HTTPS. There is no need for any specific configuration.
