You can easily create a free certificate in the Plesk web interface, which is also valid for all subdomains. We describe how to do it.

Request Wildcard SSL Certificate

  • Log in to the Plesk web interface
  • In the list, find the domain to which you want to add an SSL certificate.
  • Open the DNS management of the domain in the background. Make sure that the domain is connected to your web hosting.
  • In the Plesk web interface, click on „SSL/TLS Certificates“ for your domain.
  • Click on „Issue SSL certificate
  • In the sidebar that opens, select „Install free basic certificate from Let’s Encrypt“.
  • In the window that opens, check „Protect wildcard domain (including www and webmail)“.
  • Click on „Use for free“ and wait a moment.
  • A screen with the headline „SSL/TLS wildcard certificate from Let’s Encrypt is issued for domain XYZ“ will open.
