Installing SSL Certificate Notes

You can additionally check the SSL installation instructions provided by Sectigo Certification Authority here.

If you host your domain name with Namecheap, simply provide us with your certificate and we'll be happy to install it for you.

Please note that on all Namecheap Shared Hosting servers, a special Namecheap SSL plugin installs a 1-year free PositiveSSL certificate automatically on the newly added subdomain or add-on. It works the same way for the main domain in the newly purchased hosting account. The plugin can also be used for manual installation (in a few clicks) of PositiveSSL and EssentialSSL certificates. You can find more details on the free 1 year SSL offer in this article, and here's your reference guide on the NamecheapSSL plugin.
