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.
We do not allow login forms of any kind, and your forms cannot be restricted with an actual password or login system.
However, what you can do as a workaround is to use conditional logic to show/hide fields of your form based on an answer your users provide on a field:
With this in mind, you could use a simple Text Box or Text Area field to ask for an "access key", and show the remainder of your form to users when they enter a specific "access key" into that field.
Please let us know whether you need any further assistance, we'll be glad to help. Thank you.
