Google reCAPTCHA Is Now Invisible

The reCAPTCHA is the most popular CAPTCHA service made by Google. You've seen it a million times when you sign up a page across the web. Its primary goal is to separate humans from a bot. It challenges users by deciphering a photo of words or numbers or picking objects in a grid of photos. But that process of verifying whether you're a human or not is over because Google is changing it. Recently, the company introduces the invisible reCAPTCHA.
