What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Are you trying to keep your form private to those who only knows the password to enter the form? We don't have a direct feature for this, but a workaround can be made using our conditional logic, show/hide condition.
You can use this method: http://www.jotform.com/help/297-Show-or-Hide-multiple-fields-at-once-using-form-collapse-tool.
Add the password textbox at the top and use this textbox in the conditional logic field.
Let us know if you need any further assistance implementing this to your form.
