Google AI has become so intelligent that it can now recognize whether you are a human or a robot without CAPTCHAs, i.e. without annoying controls, like the tick in a can, or find similar…
We have all met 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 have emerged as a technique to avoid them. But they were always annoying, as it was sometimes impossible to resolve them even from people. 
Then, in 2014, Google announced “reCAPTCHA” which did not display puzzles but a simple box that you had to check. Google analyzes your behavior on the webσελίδα to determine if you are human. If it noticed something suspicious (like not finding the check box the first time) it would ask 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.
