Google reCAPTCHA v3 returns a score for each request based on interactions with your site.
Unlike v2, it does not require user interaction. Instead, it uses machine learning to analyze behavior patterns and assign risk scores from 0.0 to 1.0, where 1.0 is very likely a legitimate interaction and 0.0 is very likely bot traffic.
Website owners receive the score and can decide what action to take based on their risk tolerance.
