What is Google reCAPTCHA
Before explaining what reCAPTCHA is, you should understand what CAPTCHA is.
The first working version was invented in 1997, 6 years later in 2003, the term CAPTCHA was coined. The idea was to present a challenge to a human and ask them to complete it (usually a hard to read picture which they had to type out). That would provide the computer program with some confidence that it was dealing with a human user and not a computer or bot.
This was very successful in many ways, but presented some issues to some disabled users and also slowed down people's workflow. In many ways, it was a temporary solution that worked well for some situations.
Now let's look at reCAPTCHA (which is a form of CAPTCHA). This is a service by Google which aims to protect your website and forms from abuse which includes spam. reCAPTCHA started back in 2007 (before Google owned it), and it originally asked users to type in hard-to-read snippets of text from books or newspapers which had been scanned, this would help to translate poorly scanned books into better quality digital versions. However, it didn't take very look before bots could easily complete these challenges, which rendered the verification check much less effective.
When Google created V2 it came with a form of traffic analysis. First, it asks the user to check a box. It'll then decides to either accept it or present a challenge. The challenge would come in the form of several pictures which the user would need to click on the correct ones. For example, identify all photos with traffic lights on them. Some more advanced bots could potentially complete these too.

reCAPTCHA Version 3 is more advanced and no longer requires users to complete any tests or interact in any way. It uses advanced traffic analysis to score the user. There is a score between 0 and 1 (1 is best), by default 0.5 and above will likely be less risky traffic.
When you use reCAPTCHA v3, you decide what score is right for you.
How to set-up your Google reCAPTCHA account
Before you can use reCAPTCHA, you need to set-up an account.

Step 6. Provide the email address of the website owner(s)
Step 7. Read and agree to the terms of service. Tick the box.
Step 8. Receive alerts to your email if your integration is thought to be wrong or an increase of suspicious traffic is suspected
