Without using any package we can easily add Google Recaptcha to the laravel project

Step 1: Go to the Google reCAPTCHA website (https://www.google.com/recaptcha/admin/create) and log in with your Google account.

Step 2: Choose the reCAPTCHA v2.
Step 3: Select the “I’m not a robot” Checkbox.
Step 4: In the Domains section, enter your website domain(s) where the reCAPTCHA will be used. For development purposes, you can use “localhost” as one of the domains.
Step 5: Accept the reCAPTCHA Terms of Service, and click the “Submit” button.

Step 6: add this on .env and replace it with your site key and secret

RECAPTCHA_SITE_KEY=[your_site_key]
RECAPTCHA_SECRET_KEY=[your_secret_key]
RECAPTCHA_SITE=https://www.google.com/recaptcha/admin/

Step 7: Add this link to your head tag

<script async src="https://www.google.com/recaptcha/api.js"></script>

Step 8: Add this to your form

<!-- Google Recaptcha Widget-->
<div class="g-recaptcha mt-4" data-sitekey={{config('services.recaptcha.key')}}></div>

Step 9: Add this to the config/services.php file

'recaptcha' => [
        'key' => env('RECAPTCHA_SITE_KEY'),
        'secret' => env('RECAPTCHA_SECRET_KEY'),
    ]

Step 10: validate with this

$request->validate([
'g-recaptcha-response' => 'required'
], [], [
'g-recaptcha-response.required' => 'Captcha is required',
])
