Getting Free SSL/TLS Certificate from Let’s Encrypt

Note

This topic describes the old procedure present in Plesk Onyx. Go to the new one offered by the SSL It! extension in Plesk Obsidian.

If the Let’s Encrypt extension is installed in Plesk, you can get a free certificate for your domain from the Let’s Encrypt Certificate Authority and use this certificate to secure your domain, webmail and a “www” subdomain for the domain and each selected alias.

To get a free SSL/TLS certificate from Let’s Encrypt:

  1. Go to Websites & Domains > Let’s Encrypt.

  2. Specify the email address that will be used for urgent notices and lost key recovery. By default, the email address of the subscription owner is used.

  3. Specify if you want to include an alternative domain name for the domain and each selected alias, for example: www.example.com for example.com. We recommend that you select this checkbox.

  4. Specify if you want to include webmail, for example: webmail.example.com. We recommend that you select this checkbox.

  5. If there are domain aliases, select the ones that you want to include in the certificate.

  6. Click Install to get and install the Let’s Encrypt certificate for the subscription.

Now that the certificate has been installed, you may use it to secure your site:

  1. Go to Websites & Domains and click Hosting Settings.
  2. Select the Let’s Encrypt certificate you have just received from the Certificate menu and then click OK.
