What Is Captcha? What Is reCAPTCHA? Adding Captcha to WordPress

What a captcha is, and related information, are of great interest to many people. Using Captcha with WordPress brings many standout advantages and practical value. That is why understanding the relevant information helps you manage the website and keep it running as the job requires.

What is a captcha?

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is an image containing a hard-to-read piece of text, used for an automatic Turing test to tell computers and humans apart. By asking users to type the text from a distorted image, it can tell accurately whether the user is a computer or a human.

Characteristics of a captcha

Captchas are now extremely common, found on websites in many fields. They have distinctive features that stand out:

• A captcha is distorted and unclear, and you have to look carefully to make out what it says.
• A typical captcha can only be seen and read by human eyes.
• A checkbox such as “click here if you are not a robot” tells humans and machines apart, but it is not a captcha.

How does a captcha work?

A captcha works on a simple basic principle: it uses language rules or human slang that computers and the internet cannot understand. That separates people from machines effectively, as the job requires.

As a result, a captcha helps block malware, bots or computers programmed to attack certain systems. Entering the captcha stops illegal intrusion, which cannot continue unless it passes this verification step that looks simple but is very useful.

Recent statistics show humans enter captchas correctly about 80% of the time, while programmed computers or bots manage only about 0.1%. This blocks harmful actors effectively.

Why use a captcha on your website

Today, most services, large or small, use captchas, and users hardly mind stopping to verify one anymore. The widespread use of captchas in verification brings many practical benefits, and knowing them explains why you should use a captcha. They are:

• Anti-spam: this is one of the simplest but most common attack methods. Spam comments, mass account registrations and fake bulk purchases can be better controlled. With a captcha, attackers have to be real people, so they spend much more time, which solves the problem and makes spam easier to stop.
• Protecting data and information: blocking automated access by computers and bots helps protect important information and data on the website. It is very widely used by websites to guard their data gateway.
• Ensuring real interaction: when you run a survey on your website, a captcha keeps computers out of it. That prevents skewed results from large numbers of computers joining the survey, and prevents bandwidth being used up and slowing the site for real visitors.

What is reCAPTCHA?

reCAPTCHA is an improvement on captcha combined with scanning technology. Instead of requiring each user to confirm random characters, it shows full images and blurred numbers that only human eyes can read and identify correctly.
