What is CAPTCHA and How Does it Work?

CAPTCHA is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”. It is a type of challenge-response test used in computing to ensure that the response is not generated by a computer.


The process usually involves one machine (the ‘interrogator’) asking a question and another machine (the ‘respondent’) providing an answer.

If the answer is correct, the respondent is considered to be human. If the answer is incorrect, the respondent is considered to be a computer.

One example of a CAPTCHA test is the ever-popular game show, Jeopardy!. In order to win the game, contestants must provide an answer to a question posed by the host. If the contestant’s answer is correct, they win the game. However, if their answer is incorrect, they lose. This type of CAPTCHA test ensures that only humans can win the game.

Another example of a CAPTCHA test is when you are asked to identify a series of numbers or letters that are displayed on an image. This type of CAPTCHA test ensures that only humans can read and understand the text.

CAPTCHA tests are used in many different online applications such as online polls, registration forms, and even in some online games. They are also used to control spam on message boards and blogs.

By using a CAPTCHA test, we can ensure that only humans can post comments or messages on these online applications.

Why Do You Need to Add CAPTCHA to Contact Form?

A CAPTCHA is a short, simple test that can be used to determine whether a user is human or not. By requiring users to enter a CAPTCHA, you can help to ensure that only real people are submitting your contact form.

This can be important for a number of reasons.

First, it helps to prevent spam submissions. Spammers often use automated programs to submit forms in bulk, and a CAPTCHA can help to screen out these unwanted submissions.

Second, it can help to protect your form from being hijacked by malicious bots. By requiring a CAPTCHA, you can make it more difficult for bots to access and use your form for nefarious purposes.

Finally, a CAPTCHA can also help to improve the security of your website. By ensuring that only human users can access your forms, you can help to reduce the risk of attacks such as phishing and brute force attacks.

As you can see, there are many good reasons to add a CAPTCHA to your contact form.

Adding CAPTCHA to the contact form is therefore a good way to protect your site from spam.

Here’s how you can do it: 

First, add a new field to your contact form that will be used for the CAPTCHA test. This can be a simple text box or an image field.

Next, create a CAPTCHA test that will be displayed in this field. There are many different ways to do this, so consult with a developer or use a service such as reCAPTCHA (

Finally, add some code to your form handler that will check the user’s input against the correct answer for the CAPTCHA test. If the answer is correct, then the form submission can be processed normally. Otherwise, the submission should be rejected and the user should be notified of the error.

By following these steps, you can add CAPTCHA protection to your contact form and help keep your site safe from spam submissions.
