# How to Add a CAPTCHA to your Form

![Form CAPTCHA](/_astro/form-captcha.C7IWrMNH_1B2Ptx.webp)

You can enable Google CAPTCHA for your form to prevent spam entries in your form. When people fill out your form, they’ll be required to solve a little puzzle - like identifying cars on the street - and the submission will be allowed only when they prove that they aren’t a robot.

To add a CAPTCHA field to your form, open the [sidebar](./configure.md) inside Google Sheet and expand the `Advanced Settings` section. Turn on the option that says “Include CAPTCHA” and save your changes.

The CAPTCHA in forms is powered by the Google reCAPTCHA project.
