Google ReCAPTCHA V3 Usage In Asp.Net Core MVC

How To Use

You can use this repository two ways:

You can clone or fork this repo and than you can change code what you want
You can look over code and than implement your code. Note that this is an example repository.

Explanation

First, record to google recaptcha with your google account. Register your site there and get your secret and site key.
Then edit GoogleRecaptcha configuration in applicationsettings.json. Also you can change Threshold value.

"GoogleRecaptcha": {
    "VefiyAPIAddress": "https://www.google.com/recaptcha/api/siteverify",
    "Sitekey": "YOUR-GOOGLE-SITEKEY-HERE",
    "Secretkey": "YOUR-GOOGLE-SECRETKEY-HERE"
  },
"RecaptchaThreshold": "0,5"

Then you can add your UserService.

I set 0.5 for this example. If get to you score is less than 0.5 from Google API, return error page. If score is greater that 0.5 and username-password pair is correct, you are login. Devto Post: Post
