Can I create login form

Also, is there a way to put a login and/or password on the form so that you have to log in to fill out the form?

We do not allow login forms, or forms that would ask and collect passwords of any kind. Please refer to our terms of use.

Or if a form was made to steal user login credentials. All these activities are considered as Phishing and any account along with the guilty forms will be suspended immediately.
