Fortunately today we will discuss in-depth Captcha for WordPress websites and you’ll have a better knowledge of Captcha and its whereabouts.

But, before jumping right into the blog we should understand the concept of Captcha first. We tried to cover all the possible aspects and elements related to it.

Let’s proceed with no delays, spammers are just around the corner!!

Understanding the Concept Of CAPTCHA

Captcha stands for “Completely Automated Turing Test to Tell Computers and Humans Apart”. The meaning is exactly the same. This computer program can tell the difference between a human and an automated user by conducting different types of tests. These tests are quite easy to take and pass but difficult for automated users or bots to process.

As we mentioned before, there are different types of Captcha but the traditional and commonly used one is — where a user a shown a distorted image that has different alphabets or numbers. And, then asked to decode them and type the correct answer in the box. This is commonly used by all the websites but it is easy to comprehend by all the users.

Today there are new advanced versions of Captcha as well, and we discuss this in the following sections of this blog.

What are Bad Bots?

Any bot that has malicious intentions or can have a potentially negative purpose is regarded as Bad Bot. They can steal your content, post spam on your website, overload or even hack your server. These bots can be classified as Spam bots, Content Scrapers, Brute Force Attack bots, and DDoS bots.

While some of these might not inflict any major damage to your website, others might leave a very damaging impact on your website. Hence, it is suggested you deploy necessary measures to avoid these bad bots. Captcha is one of them.

What Is Google’s reCAPTCHA?

No doubt Captcha is beneficial for safeguarding the website, but it comes with its cons as well. Sometimes the users might get irritated if the Captcha test is too difficult to pass. There are situations where the alphabets are too distorted to decode, and the users might just leave your website. This can take a toll on your website’s performance and negatively impact the UX (user’s experience).

In 2014 to solve this problem Google introduced the Google reCaptcha login system or the No Captcha reCaptcha for the users to implement on their WordPress websites.  This acted as a successor to the traditional computer program.

The new system made the entire system less complicated and time-effective. The users or the visitors, now just tick the box next to the “I am not a Robot” text to confirm their legitimacy.  But why reCaptcha? It is easier for the users and after than the most traditional Captchas.

Google has proved to be the best advocate for excellent user experience. It always tries to come up with something or the other just to make the entire experience better. In 2018, Google introduced “invisible CAPTCHA”. This computer program can detect bots without requiring any immediate action on the part of users.

How to Add CAPTCHA for WordPress Websites?

Let us finally address the problem statement here. Individuals and new users are not aware of the steps to add Captcha for WordPress websites. We have already established why protecting your website from spammers and bots is important. So, let’s just jump to the steps.

Step 1: Install the WordPress CAPTCHA Plugin

We are assuming that you have already set up your WordPress website. But, if you are confused about setting up your website? We have the perfect resource for you!

After successfully setting up your website. You must protect it as well. The easiest way to implement Captcha to your WordPress site is by adding a plugin. There are a lot of different plugins to choose from. But, considering installing a plugin for your site there are certain points to consider. We have mentioned some of them for you to go through.

1. The very first thing to consider is which of these Captcha plugins suit your website working. As we discussed the traditional Captcha plugin is not as user-friendly as Google’s reCaptcha plugin is, so choose wisely!

2. The plugin that you’re going ahead with should work on all the areas of your website.

3. Ensure that the plugin works anywhere,  you’ve added a form. This will stop the spammers and bots from signing up for your website.

To install the plugin, head over to your WordPress dashboard. Then, select the “Plugins” option on the left side. After selecting the option click on “Add New”, and you are all set to install the plugin of your choice.

Step 2: Integrate Your Account With Google reCAPTCHA

After successfully installing the plugin, it is now time to finally implement it. Keeping in mind the above points, users should go ahead with Google’s reCaptcha plugin because it is convenient and user-friendly.

In this step, we will activate the plugin. After activating it, you’ll need to create your Google reCAPTCHA (assuming you’ve selected that plugin or a plugin that uses one). Now, the user must head over to the Google reCAPTCHA admin console, and fill out the registration form:

register recaptcha

It is advised to the users to read the form carefully and fill up the form accordingly. You will be asked to select between the “v2” i.e reCaptcha version 2 or “v3” i.e. reCaptcha version 3. But what is the difference between them? It is quite simple, version 2 means, you are enabling the users to verify themselves via a score. And, version 3 means, you are enabling the users to verify themselves via a challenge.

The selection entirely depends on your choice, but always remember to give user experience the top priority here. After successfully filling up the form, click on the submit button. The user can now copy the “Site Key” and “Secret Key”. You can copy this key because you use this later on.

The keys that have been shown in the picture above picture need to be copied and entered into your WordPress Captcha settings. Now, the process can be different as it depends on the plugin that you use. But it is easy to find your way to find around the plugins’ settings page.

Now, add these keys, and don’t forget to click on the “Save Changes” to confirm all the settings.

Step 3: Configure the Settings to Protect Key Areas

After successfully filling up the registration form, and installing the plugin we may now jump to the next step i.e. enabling Captcha settings to the specific areas or parts of your website.

If you are installing Google’s reCaptcha plugin, you’ll be given a list to select from. Here you can select the important areas where you want to implement this computer program to protect your website.

Types of CAPTCHA

types of captcha

As of the current date, Captchas fall into three major categories— text-based Captcha, picture-based Captcha, and audio-based Captcha. We will take the liberty to explain each one separately for your better understanding.

1. Text-based Captcha

This is the traditional and original way of verifying humans. These captchas use alphabets, numbers, certain capitalized phrases, or a random combination of alphabets and numbers.

text based captcha

These phrases are often presented in an alienated way so that it is difficult to interpret or decode. The process of alienation involves rotation,  scaling, and distorting characters. It also involves overlapping characters with an amalgamation of elements such as color, lines, arcs, or dots. This is important because it provides protection against spammers and hackers with insufficient text recognition algorithms but the drawback here is that it can also be difficult for humans to interpret.

2. Picture-based Captcha

This type of Captcha was introduced to replace the traditional text-based captcha, as it was difficult and time-consuming for the users to interpret. Picture-based Captcha is when the computer program uses graphical elements like images of animals,  shapes, and scenes to verify the user.

picture based captcha

The users are basically asked to identify a certain animal and shape from the given image or pick the odd one out. This was introduced because it was easy for the users to understand than the text-based captcha. But it has its own share of pros and cons. It is difficult for a visually impaired individual to solve these. But, it has resulted to be an effective option to secure your website because the bots require both semantic classification and image recognition.

3. Audio-based Captcha

These were developed especially for visually impaired users, who were unable to take text-based and picture-based Captcha tests. Sometimes there is a combination of both text-based and audio-based captchas, where the users are given an option to select whether they want to hear the written alphabets or not.

Wrapping Up

Keeping all the factors and elements in mind. It is extremely important to add Captcha for WordPress sites. It is not as difficult as it looks.

Let’s now narrow it down to three basic steps:

  1. Set up Your WordPress Site and download the Captcha plugin
  2. Get Google’s reCaptcha to use with the plugin
  3. Integrate and use it to protect the important parts of your site

That’s all you need to do in order to build a security shield to protect your websites and the users and their personal information. It might seem a small process but it is important to incorporate because precautions are always better than cure!
