Google reCAPTCHA v3 with the ability to detect bots without user interaction announced

Google reCAPTCHA v3

Google has introduced the reCAPTCHA v3, which is its newest API that helps you detect abusive traffic on your website without user interaction. Instead of showing a CAPTCHA challenge, reCAPTCHA v3 returns a score so you can choose the most appropriate action for your website.
With reCAPTCHA v3, Google is fundamentally changing how sites can test for human vs. bot activities by returning a score to tell you how suspicious an interaction is and eliminating the need to interrupt users with challenges at all. reCAPTCHA v3 runs adaptive risk analysis in the background to alert you of suspicious traffic.

reCAPTCHA v3 introduces a new concept called “Action”—a tag that you can use to define the key steps and enable reCAPTCHA to run its risk analysis in context. In the reCAPTCHA admin console, you can get a full overview of reCAPTCHA score distribution and a breakdown for the stats of the top 10 actions on your site.

reCAPTCHA v3 will provide you with a score that tells you how suspicious an interaction is. There are three potential ways you can use the score. First, you can set a threshold that determines when a user is let through or when further verification needs to be done. Second, you can combine the score with your own signals that reCAPTCHA can’t access—such as user profiles or transaction histories. Third, you can use the reCAPTCHA score as one of the signals to train your machine learning model to fight abuse.
