We have a website and we'd like to check if the certificate installed is a wild-card certificate or tied to the specific URL only. Could this be checked in an easy way?

Click on the padlock in the URL bar and view the certificate. To do this in Chrome you click on the Connection tab then Certificate Information . Check that the Common Name (CN) contains a * in front of your domain name.
A SSL/TLS Wildcard certificate is a single certificate with a wildcard character (*) in the domain name field. This allows the certificate to secure multiple sub domain names (hosts) pertaining to the same base domain. For example, a wildcard certificate for *. (domainname).com, could be used for www.
To issue a wildcard SSL/TLS certificate: Go to Websites & Domains, find the domain you want to secure, and click Let's Encrypt. Select the “Issue wildcard certificate” checkbox and select the domain aliases you also want to secure (if any).

Click on the padlock in the URL bar and view the certificate. To do this in Chrome you click on the Connection tab then Certificate Information.
