Let’s Encrypt is a free, automated, and open certificate authority (CA) that provides TLS/SSL certificates for websites. These certificates are used to encrypt communication between a website and its visitors, ensuring that data is kept private and secure.
Let’s Encrypt certificates are valid for 90 days, after which they must be renewed. The process of renewing a Let’s Encrypt certificate is simple and can be automated using a variety of tools. However, it is important to note that a Let’s Encrypt certificate can only be renewed if the domain name associated with the certificate is still active and pointing to the same server.
