How to secure a cPanel-enabled account with a Let's Encrypt SSL certificate
This article discusses how Let's Encrypt can automatically generate, install, and renew SSL certificates on a cPanel-enabled hosting account.
Please note that A2 Hosting, in order to provide consistent and reliable user experience, is switching from Let’s Encrypt to Sectigo for all newly provisioned accounts. Existing accounts will also make the change to Sectigo certificates sometime in the near future. The certificates are equal in terms of trust level, validity, and how they are used. You should see no impact on your site, and the only difference is that the padlock in your browser will now say “cPanel Cert Issued by Sectigo” instead of “Let’s Encrypt."
Let's Encrypt is also available for hosting plans using the Plesk control panel, though it is not enabled automatically. For information about managing Let's Encrypt with Plesk, please see this article
About Let's Encrypt
Let's Encrypt is part of an initiative to encrypt as much World Wide Web traffic as possible. It is designed to make creating, installing, and renewing SSL certificates a simple and straightforward process.
Although Let's Encrypt SSL certificates are signed by a valid CA (certificate authority), there are some significant differences these certificates and those issued by a traditional CA. For more information about these differences, please see this article
Using Let's Encrypt
Let's Encrypt is enabled for all new and most existing Webhosting and Reseller cPanel accounts. To see if Let's Encrypt is enabled for your account, click on the SSL/TLS icon in the Security section of cPanel. Then click Generate, view, upload, or delete SSL certificates. Let's Encrypt will appear in the Issuer column on the next page unless non-Let's Encrypt certificates were previously installed.
When Let's Encrypt is enabled for your account, you do not have to do anything else. The entire process of generating, installing, and renewing SSL certificates is done automatically. (The server has a process running that automatically renews Let's Encrypt certificates every 90 days so they stay valid.)
Certificates can take up to four hours to generate for a new domain. If your site needs a certificate sooner, please reach out to A2's support team
who will be happy to assist with publishing the certificate as soon as possible.
When Let's Encrypt is activated for a cPanel account, certificates are created for every existing domain and any domain that is added later.
When Let's Encrypt is enabled for an account, it does not overwrite any existing SSL certificates that are already installed on the account. All non-Let's Encrypt certificates take precedence, and are enabled before any Let's Encrypt certificates.
Let's Encrypt is enabled by default, but there are instances when it cannot automatically generate an SSL certificate for an account. These include:
