Restricted access to fill the form

Hi there,

I have a question regarding access to the form: we need to make sure that each person we send the form to, fills it just once and does not pass it to others to fill the form too. How can we guarantee this restriction?

Best,

Nuno

We can not prevent the user from sharing with others the direct link of your form, or the link of the page where you have embed it. 

We can only restrict multiple submissions from the same person: https://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form
