Benefits of installing an SSL certificate on your WordPress website

  1. Protect your users’ data: If an SSL certificate is installed, your WordPress website’s data travels through the internet with 2048-bit (or more) encryption. No computer or hacker in between can read your users’ encrypted data. Only the intended recipient (users’ browser or your server) can decrypt and read the encrypted data. The data may be credit card-like necessary payment details, user input with a contact form, or a simple login form.

  2. Display PADLOCK: Installing an SSL certificate is not optional anymore, even if your WordPress website doesn’t accept credit cards. Since July 2018, with version 68, Google Chrome has started to mark all HTTP (no SSL) websites as ‘Not secure’, even if it doesn’t accept user input. All other browsers followed the same path. When users visit an SSL-secured website, all browsers display a secured PADLOCK in the address bar.

  3. Boost the Search Engine Ranking: Google and other search engines aim to create a secure web. So, search engines now favor SSL-secured HTTPS websites and discourage insecure ones in the search results. If your WordPress website doesn’t have an SSL certificate installed, you are missing something significant regarding SEO and staying away from potential customers.

  4. Gain the trust of your users: If users see the secured PADLOCK and HTTPS connection in the URL, they are assured that your website is secured. Now you are gaining the trust of your potential customers. They are confident to purchase your product or service.

How to generate a Free SSL Certificate

Generating a free SSL certificate is straightforward. Please follow the steps below:

  1. After the previous step, you’ll be redirected to the Generate SSL page (in most cases). Otherwise, navigate to the ‘Auto-Install Free SSL’ menu in the sidebar, and click the ‘Generate SSL’ option. Screenshot here.
  2. On the next page, i.e., the ‘Generate Free SSL Certificate’ page, read & agree to the Let’s Encrypt™ Subscriber Agreement and Terms of Service & Privacy Policy by clicking the relevant checkboxes. Then click the ‘Generate Free SSL’ button and ‘OK’ in the confirmation dialog box. Screenshot here.
  3. Wait a few seconds. Then you see the second step: ‘Verify Domain’. Please check the screenshot. You have two methods, HTTP-01 and DNS-01, to verify your domain ownership. You need to complete any one method. We are discussing only the HTTP-01 method, the most popular, easiest, and time-saving method.


Please follow these steps:

  • Log in to your web server with an FTP client (e.g., FileZilla) or the file manager of your web hosting control panel.
  • Browse to the document root of your WordPress website. It will be like: /home/username/public_html/wp-site . Create a directory, ‘.well-known’ and another directory, ‘acme-challenge’, inside the ‘.well-known’ directory.
  • Click the links’ Challenge File 1′ and ‘Challenge File 2’ to download the HTTP-01 challenge files. Please remember that if the www. alias of your WordPress website doesn’t point to your web server (i.e., offline), you get only one challenge file.
  • Upload the downloaded challenge files to the ‘acme-challenge’ directory.
  • Uploaded files should be available at ‘Link 1’ and ‘Link 2’. Please click the links. The content/text of the links should EXACTLY match the content of the downloaded files. If it matches correctly, click the ‘Verify Domain & Get SSL’ button, and in the confirmation dialog box, click ‘OK’.

Now wait a few seconds, and you will see a free SSL certificate has been issued to your WordPress website. The page looks like this screenshot. Download the SSL, Private Key, and CA Bundle files (.pem) by clicking the links.

After this, log in to your web hosting control panel and install the SSL certificate on your WordPress website.

The options will differ if your web hosting control panel is anything other than cPanel and Plesk, but the concept is similar.

NOTE: The free SSL certificate issued by Let’s Encrypt™ expires in 90 days. So you need to spend time repeating the process of generating and installing an SSL certificate every 60 days. They recommend renewing 30 days before expiry.

Click the ‘Re-generate (renew) SSL’ button to start renewing.

However, the premium version of this plugin generates (issue/renew) and installs the free SSL certificate automatically. Please check the video tutorial (1:42 min) below and see how easy it is.

How do I install the ‘Auto-Install Free SSL’ plugin?

Please check the installation tab.

Does installing the free SSL plugin will instantly turn my site into HTTPS?

Sorry, it doesn’t. Installing the plugin and installing SSL certificates are two different processes. After installing this plugin, you need to do some steps. Please check the ‘AFTER ACTIVATION’ section in the installation tab.

However, the Premium plugin installs SSL certificates with complete automation. Please check the video tutorial (1:42 min) at the top of this page and see how easy it is.

My website doesn’t accept credit cards. Why do I need an SSL certificate?

Please check the ‘Benefits of installing an SSL certificate on your WordPress website’ above.

How do I generate a free SSL certificate?

Please check the installation tab. This documentation is for the free version of the plugin.

If you want complete automation, please check the Premium version’s video tutorial (1:42 min) at the top of this page.

How do I install an SSL certificate on my WordPress website?

Please check the installation tab.

I see a blank page when I try to generate an SSL certificate. How can I fix it?

Please check the log. It is located in the plugin menu. Most probably, you see an error saying ‘unable to register the account’ along with the following text in the log:

Let’s Encrypt™ API throws this error if an invalid email was set as the admin email of your WordPress website, for example, “yourname@yourdomain.mamp” or “”. Let’s Encrypt™ expects we should register an account with a working email.

To fix this, please update this plugin to the latest version and try generating the SSL again. Then you’ll get a text field to update the admin email address.

Feel free to contact us through the WordPress support forum if you still need help with any issues (with the complete log).

I have installed an SSL certificate but still don’t see any PADLOCK in the browser’s address bar. Why?

Please visit the plugin’s ‘Force HTTPS’ page and click the ‘Activate Force HTTPS’ button.

How do I deactivate the HTTPS redirect?

Please click the ‘Revert to HTTP’ button on the plugin’s ‘Force HTTPS’ page.

Alternatively, open the email you received after activating the HTTPS redirect (or Force HTTPS) and click the link to deactivate HTTPS redirect and revert to HTTP. The subject line of that email is “‘Auto-Install Free SSL’ has activated Force HTTPS on your website”. [Replace with your WordPress website’s domain].

[Pro] Why do you need my cPanel password (or API Token) when other Let’s Encrypt clients don’t?

All other Let’s Encrypt clients who auto-install free SSL certificates need root access, 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.

cPanel username and password (or API Token) are required to install the free SSL certificate with the cPanel API automatically. 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 (or API Token), this plugin will do this repeated job automatically. All your credentials remain safe in your database. Moreover, ‘Auto-Install Free SSL’ encrypts the password (or API Token) before saving it in your database.

[Pro] Does this WordPress plugin send the cPanel username and cPanel password (or API Token) 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 WordPress team approved it after the audit. Please feel free to audit yourself too.

[Pro] How do I create the cron job for automation?

You don’t need to set the Cron Job manually. It works by default (from version 3.0.0). However, ‘Auto-Install Free SSL’ can add an optional cron job with one click from your WordPress dashboard (available for unlimited sites license).

[Pro] I received the confirmation email but didn’t receive the cron output by email. Why?

Since version 3.0.0, You can access the cron output by clicking the ‘Log’ menu.

If you have an unlimited site license and created a cron job manually, ensure you have provided your email address in the ‘Cron Email’ section of the Cron Jobs page of cPanel.

Hands down the best SSL Installer for WordPress.It's not fully automatic, you need to enter your directory and Cpanel, but there are easy-to-understand tutorial videos. Only plugin that solved the error message I received in the Firefox browser for the SSL on my website.

They should have to remove free from the title of this plugin, as it no longer does anything useful in the free version. Costs $27/year to actually install a certificate now. Thanks plenty for the years of actually free service, but now I've swapped to an actually Free SSL Certificate for Wordpress.
