Zoho Forms CAPTCHA is a simple security check that ensures only human users can submit the form by preventing bot access.
This CAPTCHA displays a sequence of intentionally distorted alphanumeric characters in an image. Bots struggle to interpret this warped text, but a human can usually read it and type the correct sequence into the field to pass the check. If the characters don't match, the user is prompted to try again, effectively blocking the bot from submitting the form.
The use of this test is common on login forms, account signup pages, and anywhere secure data collection is necessary.
