The difference between our certificate (that is self-signed) and other SSL providers’ signed certificates, are that our ones aren’t trusted in many browsers, and others can be supported from browsers. If you want to install a SSL certificate if you own one, you can do that by following these steps, or use Cloudflare.
If you trust security, then I recommend installing a SSL certificate, instead of using our self-signed one.
Cloudflare is a CDN, security and protection layer for your website, that also offers SSL certificates installed on their network for free.
