<h3>External Services</h3>
This plugin optionally connects to the Google reCAPTCHA Enterprise service for bot detection on authentication forms (registration, login, and password reset).
When data is sent: When the <code>MELMIUM_RECAPTCHA_ENABLED</code> constant is set to <code>true</code> in <code>wp-config.php</code>, a reCAPTCHA token is sent to Google’s servers each time a user submits an authentication form.
What data is sent: The reCAPTCHA token generated by the user’s browser and the site key configured for your project.
