ReCAPTCHA what is it?

The name reCAPTCHA, is a combination of the English words reliable and CAPTCHA (verification test). It is an advanced security system that helps websites distinguish real users from bots. Using a variety of verification tests, reCAPTCHA identifies whether interactions on the site come from humans or unwanted computer programs.

Types of reCAPTCHs

Different types of reCAPTCHy are available:

ReCAPTCHA v2: this is probably the most recognizable version, where the user knows that their authenticity is being checked. It comes in 3 versions:

  • Checkbox: the user must check the box I am not a robot in the checkbox that appears. He can then move on immediately or complete the CAPTCHA test (e.g., select the appropriate images).

  • Invisible: reCAPTCHA works in the background, only the symbol is visible on the page, indicating that the domain uses this method of user verification.

  • Android: reCAPTCHA created for Android devices, works in mobile apps.

ReCAPTCHA v3: in this version, ReCAPTCHA verifies user behavior without user interaction. The JavaScript API returns a result, so you can implement additional authentication, send a post for moderation or reduce SPAM generated by bots.

ReCAPTCHA v1 is no longer available: it was disabled in 2018.
