The captcha determines whether an online request or submission is made by a human or a computer.
This way it protects your site’s forms (registration, login etc) against bots trying to fill them in.
reCAPTCHA v2
The “I’m not a robot” Checkbox requires the user to click a checkbox indicating the user is not a robot.

This is the simplest option to integrate with and only requires two lines of HTML to render the checkbox.

reCaptcha v3
reCAPTCHA v3 allows you to verify if an interaction is legitimate without any user interaction.
