Security is a big concern for any online eCommerce store. Especially if you are using WooCommerce, you may be aware that it is open-source software, and you need to take some extra steps to ensure your store’s security. 

Adding an extra security layer to your WooCommerce store to protect it from fake or fraudulent orders is an excellent idea. These spam orders may cause you to lose money and your Google rankings. 

CAPTCHAs will help you avoid spam or fraudulent orders and improve your site’s security. 

To help you with this, I’ll walk you through the step-by-step process to add a CAPTCHA to WooCommerce checkout in today’s tutorial. It is a very straightforward process to do so. Just follow the steps mentioned in this tutorial. 

Before diving into the tutorial, let’s explore the different types of CAPTCHA. 

What is CAPTCHA?

CAPTCHA stands for ‘Completely Automated Public Turing test to tell Computers and Humans Apart.’ It is a modern technology that tells the difference between human users and automated ones (like spam bots) and ensures the site is secure.

It gives challenges or puzzles that computers find challenging but that humans find simple. For instance, recognizing squished letters or numbers or targeting a specific region to click on.

The CAPTCHA generates and displays simple front-end challenges the user must complete before accessing the site. 

The CAPTCHA allows filtering out unwanted traffic and blocking automated programs and bots from accessing your site.

So it is an excellent idea to keep such traffic away from your site. 

Types of CAPTCHA

Following are a few types of CAPTCHA. 

1. Not a Robot Checkbox CAPTCHA

To complete this CAPTCHA, the user will move the mouse cursor to the checkbox and click it. This action serves as data for the model, which decides whether you are a human. If so, great; otherwise, the user will not be allowed to access the site. 

2. Image CAPTCHA

It’s the standard for most CAPTCHA, and the one most people use. To prove they are human, users must select the appropriate image boxes from a series presented. 

Visitors can bypass the CAPTCHA and request a new one if the image or instructions are unclear.


To complete the text CAPTCHA, visitors must enter the text that is displayed in the image into the submit box to access a particular page or complete a task such as submitting a form. 

They will be taken to the subsequent page automatically if the user enters the text correctly. On the other hand, if the text is inaccurate, the system will automatically generate another text CAPTCHA that users will need to enter.

Now that we are familiar with a few most used types of CAPTCHA, let’s dive in to add CAPTCHA to WooCommerce Checkout.
