CAPTCHA
When you share a form publicly, there is a possibility of receiving spam entries in your form. To prevent spam entries, Zoho Forms provides an option to include a
CAPTCHA
in your form.
CAPTCHA
stands for
Completely Automated Public Turing Test to Distinguish Between Computers and Humans
. It's a common way to ensure that your form interacts with a human rather than a computer bot. Enabling captcha validation on your form can help you validate respondents by challenging them to enter a response before they submit a form and keeping the irrelevant data at bay. You can use the default CAPTCHA available in Zoho Forms or integrate with Google's reCAPTCHA services to protect your forms online.
