Can I make the membership form password protected?

Hi,

Yes, membership form is way possible with Jotform. However, we do not have password protection feature for the form. You may however consider this workaround but this isn't secure since the password is visible on the form source code. But if you want to continue, here's how to password protect your form using conditional logic.
