WordPress Captcha is a simple and easy tool that provides your website with a security level and helps make it secure.
In this article, we tried to cover all the aspects of WordPress Captcha, from their meaning to the Complete setup process. And How do they do it? In addition, we will introduce you to some of the best WordPress Captcha plugins that make your step process a lot easier.
Then what we are waiting for, let us begin!
What is the meaning Of WordPress Captcha?
Captcha or WordPress Captcha is simply a computer program that helps to differentiate between humans and bots. The program is specially designed to perform an easy test that humans would easily solve, but it would be tough and nearly impossible for any bot or script to solve and pass through it.
Evolution of Captcha
When Captcha was introduced to the internet, the computer program was designed only to ask users to enter the text they saw in an image. And the image can be of random numbers, words, or letters in various and distorted styles.
However, after some time, Captcha has been upgraded to a new technology called ReCaptcha. In this program, a random word has been chosen to show on the screen and uses user input that helps in the digitalization of books.
After its successful run, in 2009, google acquired ReCaptcha technology completely. And after that, this program has done an incredible job of digitalizing thousands of books.
Apart from being a useful tool that helped digitalize thousands of books, it has not gained much popularity among users. The main reason was user experience, and users find it irritating; sometimes, even users cannot find the distorted texts; hence, users cannot access content seamlessly.
So, to overcome this annoying problem, Google introduced a new program that is totally based on AI and uses user interaction to figure out humans and bots. This new Captcha program is known as “No Captcha reCaptcha.”
In google Captcha reCaptcha, you will find a simple checkbox in which human input is required. However, if your browser finds any huge suspicious traffic, it will show images of anything that a human can easily identify but is not possible for the bot.
This is all about how Google has implemented this application to distinguish between a human and a bot. Let us talk about how you can improve your security with this Captcha Tool in your WordPress websites.
Using Captcha in WordPress
More than 40 percent of the total websites on the internet are built on WordPress. Hence it is one of the vulnerable CMS that hackers often attack. They usually try to infiltrate the WordPress default security by using spam and brute force attacks.
To learn more about WordPress security, you can also check out our Ultimate guide on WordPress Website Security 101 and explore different working methods to secure your website from hackers’ attacks.
Hence, it has become essential to take strict security measures to protect your WordPress website from getting hacked or attacked. Using the WordPress Captcha tool can be an easy solution to protect your WordPress site using Various WordPress security plugins. These plugins have the potential to block any suspicious activity and block unauthorized logins.
In addition, if you like to introduce another layer of protection to your WordPress websites and registration pages, it enables password protection login that recruits anyone to get access to your website.
The major downside of this protective layer is that sharing passwords can be vulnerable to attacks, and it is not a good option for large-scale websites with members and multiple authors. However, this security layer can also get breached easily by using brute force attacks. The only easiest and the best alternative to this is using Captcha.
Built with Google’s AI technology, it has become easy to differentiate between humans and bots by presenting Captcha challenges in finding any suspicious activity.
Now you know why you should use Captcha for your WordPress website. Another question that may arise in your mind is, How can you easily implement Captcha on your WordPress website and Comparison with the default settings? Let us find out in the below sections.
Comparing between Default and Custom WordPress Login and registration page
In WordPress, the default Login or registration pages have fundamental features that let users access different sections of WordPress as per their respective user roles and permissions.
And when we talk about the WordPress default registration form, it simply lets visitors create an account on your website before proceeding to any task assigned as per their roles.
However, you also have many customization options available to customize your WordPress login or registration page the way you want. There are multiple WordPress Plugins are available that help you to customize login and registration pages easily.
You can also check out our post on “Best Way To change your Default WordPress Login URL” and learn more about customizing your default WordPress login Url.
Whether you choose to use a custom or default page on your website, I try to cover all the aspects of this blog. I guide you through the whole setup process of the reCaptcha program for both options in WordPress.
But before that, let us understand what Google reCaptcha is all about.
Understanding Google reCaptcha
Implementing the Captcha program on your website provides you with various benefits and security to some extent, but still, it lacks in some areas. Such as it has been seen that using Captcha has badly affected the User Experience. It adds an extra step and delays the whole login or registration process.
In addition, these Captcha programs have become challenging and not a great step for users suffering from eye problems or dyslexia. Due to this, most special-abled users cannot use the website and are restricted from accessing certain websites.
To counter all these downsides of using Captcha, Google comes with its new No Captcha reCaptcha.
It is a successor to the previous one that presents distorted images of words to test, but the new version asks users to click on the checkbox showing the text ” I am not a robot.”
This new reCaptcha program from Google was easier to use and super fast than the previous version. Google has not stopped at this point; they have continued to bring some more improvements and introduced a new term, “invisible Captcha”.
Introduced in 2018, this invisible Captcha has the feature to detect bots without asking for any input from the users. However, when you try to add Captcha to your WordPress website, you will have the option or freedom to implement any Captcha you want. But one thing you must keep in mind while implementing any version of Captcha on your website is that it should not affect user experience and try to make the whole process a lot smooth and enjoyable for your users.
Implementing Captcha to your WordPress website
Since I have already explained in the above sections how WordPress is vulnerable to attacks and what necessary measures a user can take, similarly, apart from enabling password protection, another layer of protection by implementing Captcha to your WordPress site would strengthen the security and helps to restrict hackers’ attacks to some extent.
