Are we able to require a login before completing a form?

We would like to set up a survey, but want the user to 'login' before they complete it. Is this possible using jotform?

Hello TGTLegal,

Please be noted that there is not built in feature to password protect any form but with a little workaround, it is possible to achieve your requirement.

Please take a look at the following thread where I have explained this workaround in detail:  http://www.jotform.com/answers/417268-How-can-I-add-password-protection-to-my-form 

Please check and try out the workaround. Do get back to us if you have any questions.

Thank you!
