The Let's Encrypt Plugin

Valid for version 84






Last modified: July 26, 2022


This plugin allows the AutoSSL feature to retrieve certificates from the Let’s Encrypt™ provider. You can use this plugin if you do not want to use cPanel’s default provider.

Let’s Encrypt can issue certificates faster than the cPanel (powered by Sectigo) default provider. It can also secure wildcard subdomains, which the default provider cannot do. However, unlike the cPanel default provider, Let’s Encrypt imposes rate and size limits on its issued certificates.

For more information, read our Manage AutoSSL documentation.


If you use the Let’s Encrypt plugin to issue wildcard certificates, be aware that there are limits:

  • This plugin does not currently secure non-wildcard domains via wildcard certificate. For example, it cannot secure the and subdomains with a * wildcard.

  • This plugin cannot use HTTP DCV challenges to issue wildcard certificates. Let’s Encrypt does not support this type of challenge. For more information, read Let’s Encrypt’s HTTP-01 challenge type documentation.

  • You cannot use this plugin to obtain wildcard certificates if you use third-party DNS hosting. You must host DNS on your local cPanel & WHM server or within the server’s DNS cluster.

  • Let’s Encrypt imposes significant rate and domain limits. You should review the rate limits before you select this provider. For more information, read our Guide to SSL documentation.
  • This plugin does not generate hostname certificates for your system’s services. It only generates SSL certificates for your cPanel accounts. For more information, read our Manage AutoSSL documentation.
  • Let’s Encrypt provides all future SSL and Wildcard SSL certificates when you select Let’s Encrypt as your default provider. For more information on generating SSL certificates, read our Generate an SSL Certificate and Signing Request documentation.
  • The Common Name (CN) entry of an SSL certificate is cosmetic and does not affect the security of a certificate.
  • An SSL certificate’s CN does not need to be the main domain. The certificate covers all domains listed in the certificate’s Subject Alternative Name (SAN) field.
