Family Protection with password / Pin

[Arciviz]

I am expecting the Revit Family Protection with password / Pin. I can use the family in the Revit. Must open with password / Pin in the Family editor.

Unless you're only looking for the functionality to only protect your families in-house (where you can install the app on all your users computers), this wish should be posted in the main Revit ideas forum instead:

Otherwise, there's no (existing) way to "protect" the family once it's loaded in to a project. You could encrypt the family file, of course, but once you start using it in a project (which would require that you decrypt it before loading it), there's no way to "protect" it.
