Why do you need my cPanel password when others Let’s Encrypt clients don’t?

cPanel username and password is required to install the free SSL certificate automatically with the cPanel API. Let’s Encrypt SSL’s lifetime is 90 days. You need to get and install another SSL certificate before the expiration of the current SSL. If you provide your cPanel username and password, this plugin will do this repeated job automatically. All your credentials remain safe in your database. Moreover, ‘Auto-Install Free SSL’ encrypts the password before saving in your database.

All other Let’s Encrypt clients who auto-install free SSL certificate, needs root access, which is a higher privilege than the cPanel user. In shared hosting, the root access belongs to the web hosting company. So those clients will not work on shared hosting.

Does this WordPress plugin send the cPanel username or cPanel password to your server or to Let’s Encrypt?

We or Let’s Encrypt don’t collect any credentials. This plugin’s source code is open for audit. The team WordPress approved it after the audit. Please feel free to audit yourself too.

If you still hesitate for the password, please set the cPanel option to NO (in basic settings). You still get the SSL certificate and automated renewal. But you need to install the generated SSL manually. You need to provide all your domain information manually too.

I installed ‘Auto-Install Free SSL’ and did everything. But the SSL certificate was not issued. What should I do?

Please click the ‘Cron Jobs’ option in your cPanel. You’ll get the ‘Cron Jobs’ page. Now look for the following text under ‘Current Cron Jobs’ section:

Case 1: If you found this line, you have created the cron job successfully. This cron job will keep the plugin’s daily job running. Now please wait 24 hours (max). You’ll get an email notification that will tell you that the SSL certificate issued and installed automatically.

Case 2: If you don’t see that text, no cron job was added. For this reason, no SSL certificate was issued. Please create a cron job manually.

How do I create the cron job?

No need to set the Cron Job manually. It works by default. ‘Auto-Install Free SSL’ has an option to add the cron job with one click from your WordPress dashboard (available for unlimited sites license and it’s optional).

I received the confirmation email but didn’t receive the cron output. Why?

Make sure you have provided your email in the ‘Cron Email’ section of the Cron Jobs page of cPanel. You can get the same cron output by clicking the ‘Log’ menu.
