How to Install and Add Cloudflare Turnstile CAPTCHA In WordPress

Turnstile is a replacement for the omnipresent CAPTCHA forms that are seen on 98% of websites. This new application accomplishes the same purpose of safeguarding you against spam without requiring you to solve puzzles or give your data to Google.

Cyberattacks, such as brute force attacks and malicious bots, can harm your WordPress website’s performance and compromise user data. We will cover three main topics:

  • Understanding Cloudflare and CAPTCHA
  • Installing Cloudflare on WordPress
  • Configuring Turnstile CAPTCHA.

What is CAPTCHA?

CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) is a security technique used to detect whether a user is human or an automated bot while accessing a website. It provides difficulties that are simple for people but tough for bots to tackle.

Cloudflare Turnstile CAPTCHA offers an additional layer of security by intercepting suspicious traffic and presenting users with a CAPTCHA challenge. This helps filter out malicious bots and protect your website from various threats, including brute force attacks and spam.
