Benefits

reCAPTCHA v2 is not going away! We will continue to fully support and improve security and usability for v2.

reCAPTCHA v3 is intended for power users, site owners that want more data about their traffic, and for use cases in which it is not appropriate to show a challenge to the user.

For example, a registration page might still use reCAPTCHA v2 for a higher-friction challenge, whereas more common actions like sign-in, searches, comments, or voting might use reCAPTCHA v3. To see more details, see the reCAPTCHA v3 developer guide.
