To get an SSL certificate with your domain name you must transfer it to where you host it, in this case with us at YorName.com.
YorName offers domain names and domain name transfers at a very reasonable price. You get a free SSL certificate, and you can use your domain with any Starter (Free), Smart or Pro site.
Go to Site Settings, the yellow gear icon at the top right of the editor, and choose "Site Address - Domain Name" ... Then, "Transfer an existing domain name to YorName.com".
An alternative for Pro Site users who have an active email account
If you don’t want to transfer your domain name to YorName, for example because you have an existing email account with another host, please contact us, we’ll be happy to create an SSL certificate for you.
