SSL is an abbreviation for Secure Socket Layer, and it is a protocol that secures communications between a web server and a browser. SSL is used to protect the data that is transmitted between the two devices.
The main benefit of using SSL is that it helps to ensure that the data that is being transmitted is safe and secure.
SSL is not required for WordPress, but it is recommended. If you are using SSL, it is important to make sure that your web server is configured to support it.
Additionally, you should make sure that your browser is configured to use SSL.
