Google reCAPTCHA v2 vs. v3

reCAPTCHA v2 asks users to check a box or undertake an image challenge to verify they are not bots but humans. It is usually used for login and registration forms. At the same time, reCAPTCHA v3 runs in the background without actual user interaction. It assigns a score based on the behavior of a given user to determine if they are a bot or not. The v3 version provides a better user experience while still ensuring strong security.

If using reCAPTCHA v3:

• Set a Minimum Score (0.0 to 1.0) where 1.0 is a human and 0.0 is a bot
• Choose Badge Position (Inline, Bottom Right, Bottom Left)
