Configure a Storefront CAPTCHA in Magento 2

Magento 2 supports administrators to set CAPTCHA requirement for each time customers log into their accounts. This CAPTCHA enables the website to avoid spam and prevents the robots from login to the website. Thus, to effectively increase your store security and build customers’ trust, you should enable Admin login Captcha and install the Security module.

In the backend, you can configure whether customers are required to enter a CAPTCHA each time they log into the website, or after several unsuccessful attempts to log in.

Ways to implement reCAPTCHA

Google reCAPTCHA can be integrated through various methods:

• reCAPTCHA v3 Invisible: Utilizes an algorithm to assess user interactions, assigning a score to determine the likelihood of the user being human.

• reCAPTCHA v2 Invisible: Verify background without direct user interaction. Users may be automatically verified but might need to choose specific images to finish a challenge.

• reCAPTCHA v2 (“I am not a robot”): Validates requests with the “I’m not a robot” checkbox.

Where can you enable CAPTCHA in Magento 2

Admins can configure to show CAPTCHA requirement for the following forms in the storefront:

• Create User
• Login
• Forgot Password
• Checkout as Guest
• Register During Checkout
• Contact Us

Importance of CAPTCHA for eCommerce Stores

CAPTCHA is crucial for Magento 2 stores due to the following reasons:

• Spam and bot attack prevention: CAPTCHA acts as a barrier against spam and bot attacks, effectively decreasing the chances of unauthorized access and minimizing fraud risks.

• Enhanced security for user interactions: By implementing CAPTCHA, the login, registration, and checkout processes are secured, ensuring that only human users can interact with the store. This safeguards sensitive information and transactions.

• Customer trust and data protection: The use of CAPTCHA demonstrates a commitment to security and data protection. This commitment, in turn, helps build customer trust in the store’s integrity and reliability in safeguarding their information.
