Types of reCaptcha
reCAPTCHA v2 Checkbox
This type of reCAPTCHA is the most widely used and protects many websites. Users are prompted to click on a checkbox to confirm that they are not a bot. Based on user behavior and data analysis, Google determines whether the action is human or automated.
reCAPTCHA v2 Invisible
In this case, the user does not see the captcha, and the verification happens automatically. Google uses various algorithms to analyze user activity and decides whether the user is a human or a bot.
reCAPTCHA Enterprise
This advanced form of reCAPTCHA is designed for business clients. It provides enhanced tools for analyzing and managing bots on the website, as well as monitoring their activity.
reCAPTCHA v3
This type of reCAPTCHA is also invisible and provides a lower level of intrusiveness for users. It analyzes user behavior on the website and assigns scores to determine the likelihood of the user being a bot. Website owners can set a threshold value for the scores at which an action is considered suspicious.
