Firefox and Chromium are both proposing the deprecation of unencrypted HTTP, which means that any user of your website will see a warning unless you have a TLS certificate.
Web Hosting accounts can have Let's Encrypt One-Click SSL feature enabled on their account, to make the creation and installation of SSL certificates a simple process that can be done with a single click. No dedicated IP, signup forms, domain verification, key generation, or complicated certificate installation! When you enable this plan on your account, you can enable SSL with a AAA certificate authority on unlimited domains and subdomains that are hosted with us.
