Getting an SSL Certificate
If you use a vanity URL, you will need an SSL certificate. Many of our customers use Let's Encrypt which is a free, automated, and open certificate authority: https://letsencrypt.org/
You can also purchase an SSL certificate from a certificate authority such as DigiCert or Symantec, or from resellers such as Namecheap. Please note that these are just suggestions and the choice is yours! :)
Expiration
Most certificates come with an expiry date. Please ensure you have set up your certificate for auto-renewal to avoid any interruptions.
