What Is WordPress reCAPTCHA?

WordPress reCAPTCHA is a security feature that filters human and automated traffic on your website. It helps prevent brute force attacks, spam comments, and protects contact form submissions from malicious bots. There are two ways to add reCAPTCHA to WordPress sites – using a plugin or embedding the Google API using code within your theme’s file.

Why You Should Use reCAPTCHA on WordPress

Security: reCAPTCHA blocks brute force attacks and spam comments, ensuring website uptime and data integrity.
