What is v3 Google reCAPTCHA in Magento 2?

reCAPTCHA v3 is a security measure from Google.

Magento 2 reCAPTCHA employs advanced algorithms that help analyze user behavior and differentiate humans from bots. These algorithms reduce the frequency with which users need to configure CAPTCHA challenges. By analyzing user actions on your website, they also prevent bots and spam. Unlike reCAPTCHA v2, reCAPTCHA v3 operates in the background. It offers an enhanced experience for genuine users.

V3 introduces a risk scoring system (0.0-1.0) that:

• Allows mostly human-like interactions to proceed seamlessly
• Applies additional verification only for suspicious activities
• Learns and adapts to evolving bot techniques

For example, a user with natural browsing behavior gets a high score ("0.8-1.0") and faces no interruption.
