Google – Will not ask to prove that you are a human

reCAPTCHA - what is it?

reCAPTCHA – a free service that protects your site from spam and abuse. It uses advanced risk analysis techniques to distinguish between humans and robots. With the new API, many people will overcome the reCAPTCHA without the CAPTCHA task (for example, enter the letters in the given image). API, or Application Programming Interface, is the interface provided by a computer system, library, or program to allow a programmer to access or exchange data through another program.

reCAPTCHA v2

reCAPTCHA v2 – the user must tick the box “I am not a robot” to prove he is not a robot. This is usually enough, but you may also need a CAPTCHA task. This type of reCAPTCHA is the easiest to integrate, making it the easiest choice.

reCAPTCHA Android

It is common to see reCAPTCHA integrated on websites. Slightly less common – reCAPTCHA, integrated with Android apps. Using this type of reCAPTCHA, it either immediately skips the user or prompts the CAPTCHA task.

Invisible reCAPTCHA

Invisible reCAPTCHA does not provide the user with the box “I am not a robot” which should be ticked. Instead, reCAPTCHA is directly used when a user clicks a button on the site. For example, the user fills out the contact form and presses the Send button. By default, only a very suspicious case may be asked to resolve the CAPTCHA. To adjust the invisible reCAPTCHA, you should change your site’s security settings using advanced settings.

The latest reCAPTCHA v3

reCAPTCHA is used for important purposes but is often a very annoying part of the site for users. They may be asked to select images that correspond to the description or to decipher the given text. Over the past few years, Google has improved reCAPTCHA to make it less intrusive (eg invisible reCAPTCHA or reCAPTCHA v2). However, the latest, third version of reCAPTCHA will remove all interactive tasks and analyze the behavior of the visitor and allocate certain points to him.

Points will be awarded based on how the user interacts with the site. So, “good” interaction is worth 1.0 points, and the interaction likely to be performed by the robot will be scored by 0.0 points. Evaluating interaction with the site can be, for example, monitoring the movement of the computer mouse.

This version of reCAPTCHA is in the Beta phase and is still being tested before the official launch. There is a debate in programmers’ forums that the Beta version fails to collect 1.0 points. In addition, many different changes can still be made at this stage. Therefore, we recommend that you do not use this reCAPTCHA yet and wait for its official version.
