Can a user save his form and finish it later?

Recently I've sent a form. Several people asked me if it was possible to save this form inbetween and come back later to finish it.

My question: Is this somehow possible?

It is indeed possible, you can either use the Auto-fill option in the form settings, or follow the guide below to enable the save and continue later, please see:
