JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
I see that you want to protect one of your forms with a password if I understand you correctly.
Your form is already very secure behind your jotform account so no one will be able to access it except you and any sub-users you give permission to view and edit the form.
Do you maybe mean from accessing it online perhaps?
You may find this useful since it's the only alternative option to protecting your forms compared to a password since we do not allow password fields to be used on forms.
