Let’s Encrypt is a free, automated, and open certificate authority (CA) provided by the Internet Security Research Group (ISRG).
By default Let’s Encrypt is not installed on cPanel and WHM, but is very easy to get up and running,
Here are the steps:
1. Login to your server with root in SSH.
2. In the command line simply run the following command:
/scripts/install_lets_encrypt_autossl_provider
The provider will now be listed under SSL/TLS > Manage AutoSSL.
