So, the reCAPTCHA team went back to the lab to develop a new, more secure, yet dramatically simplified reCAPTCHA experience. Introducing the no CAPTCHA reCAPTCHA from Google. For the first time this revolutionary new API will let real people pass through without ever seeing a CAPTCHA. Using an advanced risk analysis engine, the new reCAPTCHA effectively separates out humans from bots and is even more secure. No CAPTCHA means no frustration. People get to where they're going faster, and everyone stays happy, except bots.
