You don’t need to spend money on a recurring expensive SSL certificate to upgrade the security of your websites or apps. Let’s Encrypt is a certificate authority from the non-profit Internet Security Research Group.

If you have shell access to your servers, they provide custom instructions for your operating system using an Automated Certificate Management Environment (ACME) protocol client called Certbot.

I found it super quick and easy to install Certbot on my webserver and it can be configured to automatically renew your certificate.
