Google AI has become so clever that it can now recognize whether you are a human or a robot without CAPTCHAs, ie without annoying controls, such as ticking a box, or find the same…
We have all come across CAPTCHAs, (the name comes from the Completely Automated Public Turing test to tell Computers and Humans apart). As bots and Spammers continue to evolve, CAPTCHAs emerged as a technique to avoid them. But they were always annoying, as they were often impossible to solve even by humans. 
Then in 2014, Google announced the "reCAPTCHA" which did not show puzzles but a simple box that you had to check. Google analyzes your website behavior to determine if you are human. If he noticed something suspicious (such as not finding the check box with the first one) he asked you to solve a simple puzzle.
"Invisible reCAPTCHA" or 'Invisible reCAPTCHA' can be added hidden to an existing button on the site, and work flawlessly, understanding if you are a real person. (can also be added via a calls in the Javascript API).
So it's time to bid farewell to CAPTCHAs.
