@slovak82, I lean with @hakan_cetinkaya’s advice to check the Require authentication to see forms and submit data
as outlined in one of our previous posts:
This should be helpful if you share your form with a closed group of enumerators with their own KoboToolbox account.
But if the form has been shared with a group of users who do not have an enumerator’s KoboToolbox account, then it’s wise to clone the project and share the link of the newly deployed project, and archive the previous project whose URL has already been exposed.
