Best reCAPTCHA Plugins for WordPress in 2023 (Free + Paid)

Why implement a WordPress captcha plugin?

Are you searching for the best free Captcha plugins for your WordPress website? Captcha plugins are crucial for websites as they help prevent bad bots and malicious requests from gaining access. At times, you may want to integrate a Captcha plugin specifically for WordPress comments. Bots have become a major issue that website owners inevitably encounter. These malicious entities use bots to attempt password leaks, post spam, and scrape website content.

They typically do not target specific websites or types of websites exclusively. According to W3Tech, WordPress now powers over one-third of websites on the internet, making it a primary target for hackers and spammers. The good news for WordPress site owners is that they can easily identify and block these harmful bots by installing a Captcha plugin. As a web developer, it is important to have a basic understanding of Captcha and why it is commonly used.

A Captcha plugin is one of the most effective tools to enhance the security of your site and protect it from unwanted users, spam, and bots. While there are numerous Captcha plugins available in the WordPress repository, we have compiled a collection of the 15 best plugins that you should definitely consider to safeguard your site from bot-related threats with ease. On a daily basis, we receive thousands of spam comments on our website. To reduce this, you can either install an anti-spam plugin or add Captcha to your comment form, email form, registration form, and login form.

I recall receiving numerous spam emails through the website’s contact form. Even with the assistance of a Captcha plugin, you can protect your login form from hackers. By installing this Captcha plugin for the contact form, comments registration form, and login form, you can effectively keep hackers and spammers at bay. In this article, we will explore the best free Captcha plugins for WordPress and learn how to add Google reCAPTCHA to the contact form, comments registration form, and login form.

What is reCAPTCHA?

reCAPTCHA was created by Google to protect websites from abuse and spam. This technology distinguishes between humans and bots by conducting a test. Bots are not allowed to proceed, while humans who pass the Google reCAPTCHA test are granted entry. There are primarily three types of Google reCAPTCHA:

1. reCAPTCHA v2: This version requires users to solve a challenge, such as selecting specific images or entering text, to prove they are human. It may also include the “I’m not a robot” checkbox.
2. reCAPTCHA v3: Unlike v2, this version operates in the background and assigns a score to website interactions, assessing the likelihood of the user being a bot or a human. It does not involve explicit challenges for users.
3. Invisible reCAPTCHA: Similar to reCAPTCHA v2, this version operates in the background without displaying any visible challenges to the user. It analyzes user behavior to determine if they are human or bot.

A captcha is a test that helps combat spam by differentiating between humans and robots. It requires user interaction, such as selecting images or copying words, before allowing them to perform certain actions like downloading a file, creating an email account, validating a comment, or submitting a form. It’s worth noting that CAPTCHA is a registered trademark in the United States.

It means Completely Automated Public Turing test to tell Computers and Humans Apart.  

What are the different types of captcha?

There are various types of captchas, and here are the most commonly used ones:

• Text-based Captcha: This is the classic captcha format, where you encounter a series of distorted and sometimes difficult-to-read letters and numbers. Your task is to accurately reproduce the characters to demonstrate that you are human. On average, it takes a person around ten seconds to analyze the provided text.
• Image-based Captcha: In this type of captcha, you are presented with images and asked to identify specific objects or elements within them. For example, you may be required to select all the images that contain a particular object, such as a car or a traffic light.
• Audio-based Captcha: With audio captchas, you are presented with spoken words or numbers in audio format. Your objective is to carefully listen and accurately transcribe the characters or digits you hear.
• Math-based Captcha: This captcha involves solving a simple mathematical equation or providing the result of a basic arithmetic operation. For instance, you may be asked to add or subtract two numbers to validate your human status.
• Checkbox Captcha: The checkbox captcha is a less intrusive form of verification. It typically requires you to check a box to confirm that you are not a robot. Sometimes additional challenges, such as selecting specific images, may be incorporated alongside the checkbox.

These captchas serve as a means to differentiate between human users and automated bots, thereby enhancing website security and deterring spam and malicious activities.

The captcha by image identification. Here, you are given a word (for example, “cars”), and you must select the images corresponding to this word.

The reCAPTCHA. This system was developed by Google. To verify that you are not a robot, all you need to do is check a single box. If the system is unsure about your human status, it may present you with a small test to complete. Typically, you’ll be asked to solve a simple problem. In most cases, Google will prompt you to identify specific images from a selection, as mentioned earlier. This advancement is highly commendable as it eliminates the inconvenience users previously experienced while browsing websites. Overall, it significantly improves the user experience!

The captcha based on a mathematical problem. In this case, you are asked to solve a very simple mathematical problem, such as addition or subtraction.

The captcha in audio format, which can be offered for visually impaired users.

Do you really need a captcha on your WordPress site?

The usefulness of captcha on your website primarily depends on the effectiveness of your anti-spam plugins in filtering out malicious robot comments. If you find that your current plugins are not adequately blocking such comments, it is advisable to install a captcha. As for the placement of captcha, I recommend incorporating it strategically into the following areas of your site:

• Contact form
• Login form
• Comments section

It’s worth noting that certain form plugins provide a convenient feature called honeypot, which serves as an effective spam deterrent. With this built-in feature, you may not need to add a captcha to your forms. For example, the Gravity Forms plugin includes this functionality. However, keep in mind that relying solely on captcha installation cannot guarantee complete prevention of malicious bot activities. Implementing the practice of manually approving comments before publishing them, along with utilizing the Akismet plugin, can greatly assist in preventing spam on your site. Spam can be generated automatically by computers, but users may also post comments solely to create links to their own websites. To counter this, ensure that the following options are checked in the “Settings > Discussion” menu of your WordPress dashboard:

• Comment author must fill out name and email.
• Comment must be manually approved.

When these settings are activated, they appear as shown below:

[Image: Settings screenshot]

By implementing these measures, you can better safeguard your website against spam and maintain control over the content being published.

And a little reminder, before moving on: installing a captcha is only useful in case of problems with your comments, your contact form, or login.

Really Simple Captcha is a widely used and powerful captcha plugin for WordPress, boasting a substantial user base of 800,000. Despite its seemingly straightforward name, this plugin offers significant functionality and usefulness. Unlike other captcha plugins that rely on PHP sessions for storing states, Really Simple Captcha utilizes temporary files, allowing for seamless integration with WordPress without any conflicts. When a captcha is generated, two files are created: one to store the image file and another as a text file containing the correct answer. If the respondent types the matching answer, the plugin allows the form submission to proceed. Really Simple Captcha is compatible with various plugins, particularly Contact Form 7, and can be added to login and contact forms.

Really Simple CAPTCHA is an intuitive WordPress extension designed primarily for Contact Form 7 but can also be utilized alongside other plugins.

Once both captcha files are verified, users can submit their forms without any hindrance. It’s worth noting that while Really Simple Captcha serves its purpose effectively, it may not be the most secure option. If security is a top concern, it is advisable to consider alternative plugins. This plugin does not rely on PHP sessions for storing data and instead utilizes temporary files, allowing for easy integration with WordPress.

Total number of users: 600,000+ (as per the provided information)

This plugin is particularly popular in the realm of anti-spam, with over 500,000 active installations. Although it is free to use, it requires integration with another plugin.

However, one significant drawback is that certain interesting features are only available in the premium version, which starts at $29.99/year for use on one site. Without upgrading to the premium version, you won’t be able to take advantage of integrations with popular form plugins such as WooCommerce, Contact Form 7, Gravity Forms, BuddyPress, and more. This limitation may make it less appealing for users who rely on these integrations.
