Hi! I set Google reCAPTCHA V3 to the Login form in Net.Core 6. Did everything as in this video. https://youtu.be/hfMiM6tRaQI?si=kknfnb0iJzwVFiOG The domains in the settings when receiving the keys were set by localhost and the site domain itself. But now I always see in Login.html.cs if(ModelState.isValid) = false in the public async Task<IActionResult> OnPostAsync() method. Can anyone tell me why this is so? Maybe someone has encountered such a problem? Thanks!

Hi @Volk Volk , Firstly pls check if the login model receive the value? Then pls check and share the ModelState detailed error.
Hi! Everything works fine for me without Google reCAPTCHA. But as soon as I set [ValidateReCaptcha] to the class LoginMode:Page Model {}, ModelState.isValid always becomes false. In fact, there are no errors, except reCAPTCHA is Invalid.
ErrorMessage = "Your request cannot be completed because you failed Recaptcha verification." But I have everything registered correctly and the keys are entered correctly too.
How do you even understand this error and where to dig?

As I expected, Google ReCaptcha works (In my case) on the example of this video (I recommend).

The issue is closed.

so did you add the javascript code to the view to fetch the recaptcha token, and include on the form submit?
https://github.com/langer-jaroslav/GoogleReCaptcha.V3
also check the browser console for any javascript errors.
You are offering me a reCAPTCHA input option for Target platform: .NET Core 3.1+. I'm talking about a quick check for Net.Core 6.0. Watch the video to see what it says. You are talking about this, as far as I understand. I need the simple protection of "I am not a robot" on certain pages of the site. I probably need such protection on all pages of the site from DDOS attacks (I don't know for sure yet). https://youtu.be/ornfs__-k7E?si=bIpQskT5uMU5tBlg
I'm trying to figure out and implement a quick recaptcha that is background and does not interfere with users.
I see the following errors:
recaptcha is two parts.
first is the javascript code added to the page. this javascript calculates the score. it also must intercept the form submit and add the score token to the submit request.
server side, via validation, the token is sent to the google api to validate. this is the step that generates the validation error.
use the debugger to check if the token value exists in the postback data. if the token value is empty then the client is not running the javascript code. if it not empty, then the client javascript is probably not configured correctly.
I didn't understand a damn thing you said, but it's very interesting. ) What should I do? In the video, everything works. I just need to protect some pages from DDOS attacks like "I'm not a robot". You are suggesting some kind of incomprehensible, long-implementation scheme for Net.Core 3.1. There is some simple option for Net.Core 6? This should be implemented simply, not difficult. )
You probably mean this sequence of actions:

Maybe I need to turn on "cookie" somehow, although I don't use "cookie" on my site - and I don't want to turn on "cookie" just because of the captcha.
That's what I see in the details of the error:
Test!
you are using a 3rd party wrapper to a 3rd party library and not showing us any code, especially the required javascript on the form. please read docs and follow:
this is a test answer……
This is a looooong test comment.
And... )) Is this a Google reCAPTCHA test response?
Should I turn off the test mode somewhere? How? By the way, in the statistics I see 210 requests on January 28, 29 and 30 - they probably still pass, but my ModelState.isValid is always false.
