How can I add a WordPress reCAPTCHA without a plugin?

You can add reCAPTCHA to your WordPress website without using a plugin by following these steps:

• Go to the reCAPTCHA website (https://www.google.com/recaptcha/) and sign up for an API key.
• In your WordPress website, open the functions.php file in your theme folder.
• Add the following code to the functions.php file:

function my_custom_recaptcha() {

  echo '<div class="g-recaptcha" data-sitekey="YOUR_SITE_KEY"></div>';

}

Replace YOUR_SITE_KEY with your reCAPTCHA site key obtained in step 1.

• In the form where you want to add the reCAPTCHA, call the my_custom_recaptcha() function. For example, if you want to add the reCAPTCHA to the comment form, add the following code to the comments.php file in your theme folder:

<?php my_custom_recaptcha(); ?>

Note: This method requires some coding knowledge and it may not work with all themes and forms. Using a plugin is usually the easiest and most reliable way to add reCAPTCHA to your WordPress website.
