What is reCAPTCHA?

reCAPTCHA is a service by Google to verify humans online. CAPTCHA stands for Completely Automated Public Turing Tests to Tell Computers and Humans Apart. This technology was invented in 2000 at the Carnegie Mellon University. It helps protect websites from misuse and abuse. 

Google reCAPTCHA uses tests to set apart humans from bots. The way these tests are designed that it allows humans to solve them. But bots struggle to pass them. The original reCAPTCHA uses distorted text or image matching to set apart humans.

Today, it’s more sophisticated and could detect human connections without interaction. Currently, there are three main types of reCAPTCHA to fight bots.

  1. reCAPTCHA v2
  2. reCAPTCHA v3
  3. Invisible reCAPTCHA


reCAPTCHA v2 is the most used type of reCAPTCHA on the internet. It detects humans by offering a checkbox and other tests. These tests include identifying traffic lights, bikes, cars, etc. Also, answering simple addition math by seeing images.
