This is just fine, the dialog in which the password is given will be destroyed
right after typing it (and pressing OK, of course).

Well, I don't think I'm going to do this, it's unnecessary work, because the
above will do. The point is that if an asterisklike thing would have been
implemented (and there wouldn't be gtk_entry_set_visible) I would have used
this, it's just for a project at college, will not be used after we got our
ratings for it, I think.

Yes.
