Add Math Captcha to your Form
The Math Captcha field enhances form security, shielding against bots and spam submissions. Users solve a mathematical problem, and with adjustable complexity, you can effectively thwart bots.

Add Math Captcha to Joomla Forms
To add the math captcha to your Joomla forms, go to the main administration menu: Components → Convert Forms → Forms.

Choose the form you want to edit.

Choose the tab "Add Field" and click on the Math Captcha field in the Capcha Fields category. Save your work.

Once the field has been added to the form, you'll be able to customize it by setting the complexity as well as the error message that appears when the user types an incorrect answer.

Finally, after all the changes, save your work. Your Math Captcha field is ready!
Here's how it will look like in your form:

Why you probably don’t need Math Captcha
Without you having to do a thing, Convert Forms is already protecting your forms from spam submissions. A honeypot field is automatically added to each form by default. It's designed to catch spammers in the same way an actual pot of honey would catch flies. It's just a hidden field placed into every form and it's purpose is to make form submission fail if anything is entered into it.
