What is a wildcard SSL certificate and do I need one?

A wildcard certificate secures a domain and all of its subdomains with one cert, e.g. *.yourdomain.com covers www, shop, blog, api, staging, and any future subdomain. It’s ideal for multi-store, multi-app, or microservice setups. If you only have one or two fixed subdomains, a standard or multi-domain (SAN) cert is cheaper. We’ll advise based on how your subdomains are likely to grow.
