An SSL certificate chain, also called a chain of trust, links your website's certificate to a root certificate that browsers already trust. It's made up of three parts: your server's certificate, one or more intermediate certificates, and a root certificate. Each certificate is signed by the one above it, so a browser can follow the chain up and confirm the whole thing is legitimate.
