What is a CAPTCHA and Why Should You Use It?

A CAPTCHA is an internet security feature to ensure that the entity trying to log in or visit a particular website is human and not a spam robot. Illegal internet activity is also increasing with the growing use of the internet. Cybercriminals often use spam robots to log in and steal information from websites. The general purpose of CAPTCHA protection is to stop spam robots from accessing websites and search engines. You can learn about how to secure a WordPress website to avoid different kinds of spamming.

A CAPTCHA is a single image or a set of images from which the user needs to identify a particular object to pass the CAPTCHA test. Spam robots are not capable of reading objects from an image; only human has the understanding of doing it. Thus, the CAPTCHA test successfully prevents spam robots from logging into a website and stealing information. You can add CAPTCHA to WordPress using the plugin and the best WooCommerce themes for WordPress.

Types of CAPTCHA Security

There are a few types of CAPTCHA you can choose from and implement on your WordPress website for increased protection. In this section, we will discuss the latest and most effective types of CAPTCHA protection you may pick from. You can also choose security plugins for WordPress to enhance more security of your website.

Add CAPTCHA to WordPress: Human-Assisted OCR 

Human-Assisted OCR is currently the most popular among the widely used CAPTCHA types. ReCAPTCHA, created by Google, uses this Human-Assisted OCR CAPTCHA where the user must recognize a particular object from a set of images to be confirmed as human. For example, you could be asked to identify a number of traffic lights, fire hydrants, palm trees, trucks, etc. 

OCR means Optical Character Recognition, which allows users to read the images and pass the CAPTCHA test successfully. Many users are unable to pass the CAPTCHA test, where they have to read and input scrambled text due to visual impairment. Thus, OCR makes it easy for the general audience to be confirmed as human users.

You can use the reCAPTCHA plugin in your WordPress website to quickly and flexibly implement this Human-Assisted OCR CAPTCHA method.  The reCAPTCHA plugin is supported by all freestore WordPress themes.
