How to add Google reCAPTCHA into Magento 2
Learn how to integrate Google reCAPTCHA into Magento 2—an essential skill in today’s internet workflows. Despite various methods, reCAPTCHA remains a trusted solution for distinguishing humans from automated bots.
This challenge-response test ensures user authenticity, employing an adaptive CAPTCHA system that deters abusive activities on your site. Enhance security without compromising the user experience by creating a new reCAPTCHA implementation.
What is CAPTCHA in Magento 2?
CAPTCHA, short for Completely Automated Public Turing test to tell Computers and Humans Apart, is a tool designed to differentiate between automated bots and real human users.
It involves presenting challenges, like inputting distorted characters, that require human interpretation. This complexity prevents bots from solving the challenges, ensuring online security and deterring fraudulent activities.
In Magento 2, CAPTCHA can be deployed in various areas, including admin access and user interactions on the storefront. Magento supports both standard CAPTCHA and Google reCAPTCHA, which will be discussed later in this blog.
Overview Google reCAPTCHA
reCAPTCHA, a free service by Google, safeguards websites from spam and abuse. A “CAPTCHA” is a turing test designed to distinguish between humans and bots. While easy for humans to solve, it poses a challenge for bots and malicious software. Integrating reCAPTCHA into a site helps prevent automated software, ensuring a smoother experience for genuine users while blocking unauthorized access.
To activate Google reCAPTCHA, you must obtain a set of API keys. Before proceeding with the setup and key generation, it’s crucial to decide on the type of reCAPTCHA you want to implement. There are three options to choose from:
-
reCAPTCHA v2 (“I am not a robot”)
-
reCAPTCHA v2 Invisible
-
reCAPTCHA v3 Invisible
To enable and configure it, please adhere to the instructions below.
