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 guess you are looking for a job board type form. Unfortunately, login forms or a form that would ask for username or email in combination of a password field is not allowed in Jotform.
We allow registrations forms, but still no password field is allowed. You can find registrations forms from our form template gallery: http://www.jotform.com/form-templates/category/registration.
