What is Captcha?

A CAPTCHA is computer software that differentiates between human and automated users. It does that by imparting a check that would be pretty easy for a human person to pass but more complicated and almost impossible for automatic scripts to get right.

Initially, CAPTCHA users were asked to enter the text they used to see in the images. These images had random letters, words, or numbers with a distorted style.


So, developers tried something that would have convenient for the users. Finally, they introduced reCAPTCHA.  


The Google reCAPTCHA was introduced in 2009 to make CAPTCHA. It is helping, since, for having a secure and risk-free site.

However, it needed to fix the problem as these were still annoying for the users and almost ruined the website's user experience (UX).

As a solution, Google introduced No CAPTCHA reCAPTCHA. It used AI and user interactions to catch spambots.

reCAPTCHA has an easy checkbox for human users to click with I’m not a robot text on the login/registration form. 

Sometimes, you might experience more complex objects to be identified for other suspicious traffic, i.e., bots, such as identifying Traffic Lights, Houses, Cats, and more.

Why Use reCAPTCHA for WordPress Login and Registration?

WordPress login/registration pages often fall victim to spammers, brute force attacks, and more.

The attacker’s main motive behind the attack is to get unauthorized access to your WordPress admin area. Sometimes, the attackers crash the entire network of websites.  They do so just to get a ransom.

There are many ways to help you protect your website against this scenario, like using a  WordPress firewall plugin, adding password protection, and more. 

Google offers reCAPTCHA,  a CAPTCHA-like system, to help you protect your website from spam or abuse. It is like a shield to your website that protects you against “bots” and other “malicious software.”
