How to Secure WordPress Sites with CAPTCHA (EASY)
February 3, 2022

Hi, and welcome to another WordPress tutorial!

Today, we’re gonna learn how to secure WordPress sites with CAPTCHA (THE EASY WAY).

And by that, all we need to do is use a plugin to make this work!

But before we get into it, I want to brief you on why you need CAPTCHA on your WordPress sites.


What’s CAPTCHA & Why Do We Need It?

To start it off – CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart.”

It’s a tool you can use to differentiate between real users and automated users, like bots. Another thing CAPTCHAs can do is provide challenges that are difficult for computers to carry out, although they’re easy for humans.

These types of challenges are like:

  • Identifying Streched Letters or Numbers
  • Selecting Specific Images

And so, CAPTCHA protects you and your website by doing just that!

This is the shortest and clearest I can keep it! But if you wish to learn more about CAPTCHA, you can visit this article from Imperva on What is CAPTCHA?

Moving on!

Installing CAPTCHA to WordPress

So now that we got that out of the way, we can finally install the CAPTCHA plugin to our WordPress site!

As expected, we must be on our WordPress dashboard.

From there, navigate to Plugins and click Add New.

After clicking Add New, search for CAPTCHA 4WP.

Then you should see CAPTCHA 4WP and click Install.

Once installed, click Activate!

After the plugin is activated, navigate to Settings and click CAPTCHA 4WP.

This is what you should see:

Under Google Keys, click the highlighted word Google ReCAPTCHA dashboard.
(Which brings you to the reCAPTCHA admin page)

Once you’re on the reCAPTCHA admin page, this is what you should see:

For Label, type in your site’s name – because my site’s name is Divi Demo, I put the Label as Divi Demo.

For reCAPTCHA Type, select reCAPTCHA v2 – underneath reCAPTCHA v2, it should select automatically select “I’m not a robot” Checkbox.

For Domains, this is very easy! But with a twist.

Instead of pasting your site’s URL as:

Your site’s URL should be pasted in without the “https://”

like this:

After putting your site’s URL in, click the “+” icon to add your website.

Next, click the Checkbox that says Accept the reCAPTCHA Terms of Service.

Then click SUBMIT!

After that, you’ll be brought to this page. (Which generated the CAPTCHA Keys that we’ll be using)

Leave that tab open.

Going back to WordPress in the CAPTCHA 4WP Settings.

Under Enabled Forms, you will see that there are lots of options to choose from!

For now, we’re gonna click the checkbox for Login Forms.

After that, scroll down and you will see more settings to customize your CAPTCHA!

But we’re not gonna touch that and just hit Save Changes.

Once the changes have been saved, log out of your WordPress dashboard and this is what you should see!


Now that you have a CAPTCHA on your WordPress site, the CAPTCHAs will add an extra layer of security – that way, you can avoid getting spam or hacked. Hope this helped, and if it did, feel free to share it with your family and friends! And I’ll see you all in another blog 🙂
