Form that allow users to sign in to Facebook or Twitter?Asked by realestatecoach on September 04, 2015 at 02:51 PM
Unfortunately, it is not possible to create any sign in form with JotForm.
Just for you to know, you may like to add a Facebook Like Box widget in your form. This will ensure that the users first like your page before they can submit your form.
