Over the years, Google has utilised a number of methods to distinguish between human and bots on the web. Its take on the CAPTCHA (Completely Automated Public Turing test to tell Computers and ...
In 2013, reCAPTCHA began implementing behavioral analysis of the browser's interactions to predict whether the user was a human or a bot. The following year, Google began to deploy a new reCAPTCHA API, featuring the "no CAPTCHA reCAPTCHA"—where users deemed to be of low risk only need to click a single checkbox to verify their identity. A ...

The reCaptcha v3 is designed to not interrupt users and run automatically when pages are loaded or buttons are clicked.
A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one ...
