Can You Add CAPTCHA to WordPress?

CAPTCHA is an automated system used to verify that a user is human. CAPTCHAs are used on websites to prevent automated spam submissions. WordPress has a built-in CAPTCHA system that you can use to protect your blog posts from being submitted automatically. To activate the CAPTCHA system, go to Settings > General and scroll down to the CAPTCHA section.

Enter a unique CAPTCHA code and click the Save button. Anyone who tries to submit a post without entering the code will be sent an error message.
