AspNetCore ReCAPTCHAv3

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
