Yes, when you share the form, it’s one of your options.

Hi ScottWorld,

Many thanks for prompt reply.

OK, I had something else in mind… I’m “publishing” a form with clicking on Open Form, so it is published and accessed on web. Is it possible to protect “published” this way?

There is no “Open Form” button unless you’ve already shared it. Click on the “Share” button next to it to set your settings.

You’re not paying attention to what I’m saying. Do you see the button next to that that says “Share Form”? Click on that button.
