auth for signaling/relay server?

[hydrargyrum]

I'd like to self-host hbbs/hbbr but I don't want anybody else to use them. Is there a way to require some kind of auth to access them? (maybe just some kind of API key)

Clients need to add a key that is randomly generated on first server start:

That is from a temporary isolated test instance, no relevant key leaked 😉.

so without this key, nobody else can connect to this hbbr/hbbs?

Exactly. One will see a key mismatch error when trying to connect to a peer with a false ID server key.
