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.

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.
