How to Add CAPTCHA to Google Forms in 2 Easy Steps

Google Forms doesn't include a built-in CAPTCHA feature. To add a CAPTCHA-like mechanism, you must do it manually. 

Here's how to add a simple CAPTCHA to your form:

Step 1: Add a CAPTCHA Question

Once your form is ready, add a new question. Choose the "Short Answer" question type and write a simple challenge, such as a basic math problem, to serve as a CAPTCHA. Label this clearly to differentiate it from other questions.

For example, you can write: "What is 10 + 5?"

Step 2: Set Up Response Validation

Click the three dots in the question box to enable response validation. Specify the correct answer and create a custom error message for any incorrect attempts.

Following our example, we can set the response validation to: "Number," "Equal to" and then enter the correct answer, which is "15" in this example. You can also write a custom error text.

This example uses a basic math problem as a CAPTCHA. However, keep in mind that this method might not be as secure as automated CAPTCHA systems, and it relies on the honesty of the user to not bypass the security question.

For a more robust CAPTCHA, you might need to integrate third-party services or use Google Apps Script to implement reCAPTCHA, which would require more technical setup.
