How to Add Google reCAPTCHA (Invisible version) - Node.js 

Glad you liked it

Of course!

How so? The invisible recaptcha attached to the form button is safeguarding against bots, hence the captcha asking you to click on different images after attempting to submit the form too many times. That is how invisible recptcha works. The checkbox recaptcha, on the other hand, behaves a little different. That one does have some more safety measures on the backend, as it is a completely different security recaptcha design. You may want to look into using that one if thats what you preffer.

@@MillerHighLifez420 Bots don't need to click buttons, they can "emulate" the request browser sends when you click the button and solve the captcha. Backend should protect the endpoint by looking for captcha token in an incoming request and validating it through google service

I haven't used that one yet just V2 invisible and checkbox versions. I will have to look into it
