SSL Encryption (https)
SSL certificates create an encrypted connection between the store and the customer. They are essential for stores and websites where personal information is being transmitted.
When you create your store on the mywoocart.com subdomain, it comes configured with an SSL. When you set your store Domain, it too comes automatically configured with an SSL.
In both cases, the SSL we use is the most popular Let's Encrypt certificate, supported by major organizations like Mozilla, Chrome, Facebook, Sucuri, EFF, and others.
You do not need to use a plugin for SSL to work.
