Indeed, I did not get this point in the question. Adding local mqtt
does not affect the remote skin at all.

I don't follow "password-protected" entirely. As I see it (but haven't
done it):
you have html someplace for the skin, and it may or may not have a
password. Typically these do not have access control.
The javascript from the skin has to talk to an mqtt broker that has
the data. So one has choices (assuming one is writing code):
1) let the mqtt data be accessible without a password
2) use a static username/password and put it in the skin. This is
sort of like an API key in web parlance.
3) some scheme of new username/passwords in each page view from the
skin
I suspect most people running skins that get live mqtt data are doing
option 1, that almost all readers think option 3 is nuts, and that zero
people are doing it.
