Is satlantis open source? I’m curious how they do the username/password to nsec bunker and if it would be possible to adapt to other communities not just bitcoin digital nomads. There’s some Maori in Aotearoa New Zealand who are interested in having something similar but for Maori orgs and places here. 

Is there a library / server setup fro username / password access to nsecbunkers like the way satlantis does it?
