(Home >> SSL/TLS >> Manage AutoSSL)


This interface allows you to manage the AutoSSL feature, which automatically installs domain-validated SSL certificates on users' domains for the Apache and Dovecot services. It also allows you to review the feature's log files and select which users to secure with AutoSSL. 

  • cPanel & WHM ships with the cPanel (powered by Comodo) provider. To install the Let's Encrypt AutoSSL provider plugin, read our The Let's Encrypt Plugin documentation.

    • Certificates that Let's Encrypt provides through AutoSSL can secure a maximum of 100 domains per virtual host.
    • Let's Encrypt will issue a maximum of 20 certificates per week that contain a domain or its subdomains. If you include subdomains of a domain on more than 20 certificates, Let's Encrypt will issue those during the next window, up to the limit for that week.
    • Let's Encrypt uses the domain's alias (parked domain), not the main domain, as the common name for AutoSSL. To use the main domain as the common name for AutoSSL, you must use cPanel or another AutoSSL provider. For more information, consult the Let's Encrypt Community Support page.
  • The AutoSSL feature requires outbound access to the store.cpanel.net server over port 443. For more information, read our How to Configure Your Firewall for cPanel Services knowledgebase article.

Domain and rate limits

The AutoSSL feature includes the following limitations and conditions:


For example, the following table demonstrates these limitations for the cPanel AutoSSL provider: 

Virtual Host 1Virtual Host 2Result
200 domains 

AutoSSL will generate one certificate for the account which secures all 200 domains.

202 domains AutoSSL will generate one certificate for the account which secures the 200 domains with the shortest names.
100 domains100 domainsAutoSSL will generate a certificate for each virtual host that secures all of its domains.
100 domains102 domainsAutoSSL will generate a certificate for each virtual host that secures all of its domains.
100 domains202 domains

AutoSSL will generate two certificates:

  • Virtual Host 1 — Secures all of its domains.
  • Virtual Host 2 — Secures its 200 domains with the shortest names.

Select an AutoSSL provider

To select an AutoSSL provider, perform the following steps:

  1. Select the desired AutoSSL provider.

  2. If the AutoSSL provider requires that you accept their Terms of Service or other similar agreement, read the document and select the appropriate checkbox to agree to those terms.
  3. If you need to reset your registration with the AutoSSL provider due to security issues, select the appropriate checkbox to agree to those terms and click Reset Registration.
  4. Click Submit.

If the provider updates their Terms of Service, you may need to return to this interface to agree to them.


Enable AutoSSL

Users must use a package that includes the autossl feature to receive the free certificates. For more information about feature lists, read our Feature Manager documentation.

Feature list override

To override the feature settings and control whether AutoSSL is enabled for a user or users, perform the following steps:

  1. Click the Manage Users tab to display a table of users on the server.
  2. To enable or disable AutoSSL on a single domain, select the appropriate option:
  • Because the system adds the /etc/cron.d/cpanel_autossl cron daemon task to schedule the automatic provisioning of certificates, you may experience a delay between when you enable the feature and the installation of certificates. The interface displays the next time that the script will run.
  • The system restarts Apache after AutoSSL provisions and installs certificates for all accounts during a nightly run.

Run AutoSSL

Click Run AutoSSL for all users at the top of the interface to run the AutoSSL feature for all users with the feature enabled.

To run the AutoSSL feature for a single user, click the user's Check button in the Run AutoSSL Check column of the table.

Review log files

To review AutoSSL log files, perform the following steps:

  1. Click the Logs tab.
  2. Select the log that you wish to view from the menu, and click View Selected Log.
  3. Click Refresh Logs List to refresh the list of log files. 

The system stores the log files in both text and JSON format in the /var/cpanel/logs/autossl directory.

Frequently Asked Questions

How do I revoke a certificate?

We do not support the revocation of certificates through cPanel & WHM at this time.

Let's Encrypt won't issue a certificate for a virtual host list (website).

Let's Encrypt will only issue a certificate five times per week to a specific set of domains before it blocks any further certificates for that set of domains.

To work around this rate limitation, create an alias to a domain in the virtual host list (website) so that Let's Encrypt interprets the virtual host as a new set of domains.

Is Manage AutoSSL available for cPanel & WHM version 56?

That version of cPanel & WHM does not support deferred Apache and Dovecot configuration restarts, which results in unacceptable downtime and a poor customer experience. As such, we will not make the plugin available for version 56.
