Google reported on a new API reCAPTCHA v3, which will help to protect websites from bots. The system evaluates the user's key actions on a scale from 0.0 to 1.0 (the lowest rating means a bot, and the highest - a person) and provides data to the owner for making a decision. Google experts recommend adding it to several pages of the site, as reCAPTCHA v3 does not interfere with the user.
Google developers used the “Action” method in reCAPTCHA v3. Detailed statistics of user interaction with the site are represented in the admin panel. The site owner independently decides on actions with respect to users. The grading system allows you to:
- set the period of time after which the API will require the user to verify from the user using the phone or two-factor authentication;
- combine actions based on them with manually specified parameters for users;
- use machine learning to train AI, which distinguishes a bot from a person.
