Magento has a lot of security tools to help protect your ecommerce website from online attacks. One of these tools, CAPTCHA, ensures that people, not robots, engage with your website.
If you’ve ever been asked to identify hard-to-read text or match images before viewing a website, that was CAPTCHA doing its job.
How to set up and configure Magento 2 reCAPTCHA
Now, an even more secure option is the Google reCAPTCHA extension. Setting up reCAPTCHA in Magento 2 is vital for preventing spam bots and malicious actors from accessing your online store. This article will explain how to set up and configure reCAPTCHA by Google in your Magento 2 store.
Why is the Google reCAPTCHA extension required for your Magento 2 store?
Google reCAPTCHA and Magento 2 CAPTCHA serve the same purpose, but the Google extension enhances your website’s security even more.
The Google extension helps reduce irrelevant advertisements, suspicious registrations, and spam-filled email lists. In addition, it displays human-friendly questions users can quickly answer.
It also cuts out malicious and fraudulent order attempts during checkout. As a result, spam and fraudulent purchases decrease. Plus, it helps with website maintenance.
Features of the Google reCAPTCHA extension for Magento 2
So, what can the Google reCAPTCHA extension do for your Magento store?
For starters, it:
- Works on multiple pages in both the front and back end.
- Can implement both invisible and visible reCAPTCHA.
- Can implement both reCAPTCHA v2 and v3.
- Can serve various forms for your store.
- Has good compatibility with other Magento plugins.
How to enable and disable reCAPTCHA in your Magento 2 store
You can integrate Google reCAPTCHA into your website's back end to protect your storefront, login pages, and forms from bots and malicious brute-force attacks. Setting up and configuring reCAPTCHA for your Magento 2 store is straightforward. Here’s how to do it.
Generating the Google reCAPTCHA API keys
To enable Google reCAPTCHA in your Magento 2 store, you'll first need to generate Application Programming Interface (API) keys. You can obtain these keys for free by visiting the reCAPTCHA website.
Here are the steps to follow:
1. Go to Google’s reCAPTCHA setup page. From here, you’ll register your website, choose the reCAPTCHA type, and give this reCAPTCHA a label. Here’s also where you accept the terms and conditions of using these APIs.
2. Enter a unique name in the Label box. This unique name you provide gives you a unique identifier for the key pair and is for internal reference:
3. For the reCAPTCHA type, select the ideal option for your use case. For example, Google reCAPTCHA v3 uses a score to identify a person. And Google reCAPTCHA v2 allows you to select one of three options:
- “I’m not a robot” checkbox
- Invisible reCAPTCHA badge
- reCAPTCHA Android (smart phone)
The “I’m not a robot” option is a checkbox. The Invisible reCAPTCHA option validates the user in the background. And the reCAPTCHA Android option uses phone verification:
4. Use your Magento 2 store’s domain (that is, yourdomain.com as a pseudo code example) as the For domain value you enter:
If you have multiple Magento 2 stores, you must enter each unique web address on a separate line. For testing purposes, you can add any staging domains, local virtual machine domains, and sub-domains.
6. Next up, check the Send Alerts to Owners checkbox, which allows Google to notify you when it finds any problems or suspicious activity.
7. To finish your registration and access your keys, click Submit.
Once you click the Submit button, Google will automatically generate your chosen website's the public and private key pair. Here is the sample output:
Configuring Google reCAPTCHA v2 and v3 for your Magento 2 Admin Panel

2. On the left sidebar of the dashboard, select Stores > Settings > Configuration.

2a. Enable: Select Yes.
2b. Theme: Select either Light or Dark.

Implementing Magento 2 reCAPTCHA v2 or v3 — Invisible reCAPTCHA
To use v2 or v3’s Invisible reCAPTCHA, follow these steps:
1. Starting from the General tab (after entering the private and public API keys), select Invisible reCAPTCHA (v2 or v3) under the reCAPTCHA type dropdown menu.
2. Expand the Backend tab and set the options. Uncheck the Use System Value checkbox to set your own parameters for every field you want to configure:
2a. Enable: Select Yes.
2b. Invisible Badge Position: (Select your preferred option.)
2c. Minimum Score: Insert a value from 0.0 to 1.0. 1.0 represents the likelihood of a positive human interaction, where the value of 0.0 represents the likelihood of a bot interaction.
3. Under the Frontend tab, add Google reCAPTCHA to customer accounts. Invisible reCAPTCHA defaults to the same pages as “I am not a robot.”
Setting up custom reCAPTCHA failure messaging
To set your own failure messages, expand the reCAPTCHA Failure Messages tab and add custom messages that will display if a validation failure is detected, or validation can’t be completed:
To disable reCAPTCHA, expand the Admin Panel section. You will see the following fields:
- Enable for Login: Set Enable for Login to your preferred reCAPTCHA type.
- Enable for Forgot Password: Set Enable for Forgot Password to the preferred reCAPTCHA type to use when a user requests a password reset.
To disable reCAPTCHA in Magento 2, you can set No for Enable for Login and save the configuration changes.

By following these steps, you can disable reCAPTCHA checkout in Magento 2 for guest visitors:
1. From your Magento admin panel, go to Stores > Settings > Configuration.
2. Under the Sales tab, click on the Checkout option.
3. Untick the Use System Value checkbox in the Allow Guest Checkout field and choose No from the dropdown.
