Do clients need to sign in to JotForm to fill out a form I sent to them?

Hi there, @Wilmette!

Thanks for reaching out to us!

No, by default, anyone has your form URL is able to view/submit it.

However, if you choose to make your form private and assign it to some people, then those people need to have a JotForm account so they can view/submit form.
