If you’re running a WordPress website, keeping it secure is essential. Spam and automated bots can clutter your comments section, abuse registration forms, and even attempt unauthorized logins. One effective way to combat this is by using reCAPTCHA, a free service that protects your site from spam and abuse. This guide will walk you through configuring your reCAPTCHA API keys and integrating them into your WordPress reCAPTCHA plugin.
What is reCAPTCHA?
reCAPTCHA is a tool provided by Google that uses an advanced risk analysis engine to differentiate between human users and bots. By implementing reCAPTCHA, your website gains an added layer of security against spam and automated abuse, while allowing legitimate users to navigate your site without interruption.
There are different types of reCAPTCHA available:
Invisible reCAPTCHA: Automatically detects bots without requiring user interaction unless flagged as suspicious.
reCAPTCHA v2 (Checkbox): Users click a checkbox to confirm they are human.
reCAPTCHA v3: Operates silently in the background, scoring user interactions.
Step 1: Generate Your reCAPTCHA API Keys
To begin, you need to create API keys for your domain via Google reCAPTCHA’s admin page:
Label: A name for your reCAPTCHA setup (e.g., “My WordPress Site”).
reCAPTCHA Type: Choose the version you want (Checkbox, v3, or Invisible).
Domains: Enter your website’s domain name (e.g., example.com).
Accept the reCAPTCHA Terms of Service and click Submit.
You will be provided with two keys:
Site Key
Secret Key
On the next page click the Keys link, under Adding WordPress reCAPTCHA API to your site. You will then see your Site key, and Secret Key listed, save them for later use. For example, you can copy and paste them into a .txt document.
Step 2: Add Your API Keys to the WordPress reCAPTCHA Plugin
Once you’ve obtained your API keys, the next step is integrating them into your WordPress site. Follow these steps:
Verify the Setup After saving, test your forms (e.g., the comment or registration forms) to ensure the reCAPTCHA is working correctly. Visitors should now see the reCAPTCHA prompt when interacting with your site.
Log in to Your WordPress Dashboard Access your admin panel by visiting yourwebsite.com/wp-admin.
Navigate to the reCAPTCHA Plugin Settings
If you haven’t already installed a reCAPTCHA plugin, go to Plugins → Add New, search for “WP reCAPTCHA,” and click Install Now followed by Activate.

Click the Save reCAPTCHA Changes button.

Now when visitors post a Comment or Register for your site, they will have to complete a re-CAPTCHA validation, to prove they are human. See the examples below.
You now have a CAPTCHA system for your WordPress blog, and the amount of Spam to your site should be reduced!
