Configure Let's Encrypt in Your Magento Store
Let’s Encrypt was launched in late 2015 and provides free SSL and TLS certificates. It is approved by IETF (Internet Engineering Task Force). With Let’s Encrypt, there is no complication in the configuration of SSL. You need to reissue the certificate installed through Let’s Encrypt after three months, before it expires. You can auto renew your Let’s Encrypt certificate with Cloudways auto renew option. Cloudways warns you 15 days before the expiration of your Let’s Encrypt certificate.
