Currently I have a Nucleus+ at home, and this is not a problem. But I’m planning to set up a Nucleus at the office, and I would like to avoid having free access for everyone there (a few 1000). With current solution you can screw up the Nucleus; or get access to all the music.
I would actually prefer the option to set password on the Roon Core as well (default like today, but with option to set if you need it).
