Can we set Password for form collaboration?

I have multiple collaborators on a form, but I would like to make a secondary step to make sure that the form we created isn't edited inadvertently. Is this possible? Thanks!  

Unfortunately its not possible with form collaboration since updates are done in real-time and once you have shared the form for collaboration then any changes made by user then are updated in real-time.

Since changes made by users are saved automatically we recommend the team collaborating on a form to have proper communication  structures in place when building of editing the form.
