I want to host a Vaultwarden (or Bitwarden if necessary) instance, but it keeps asking for a domain and a SSL certificate. I dont own a domain and dont want to enable port forwarding on my router to expose it to the outside.
Is it possible to host a instance only internally and access it via the IP or a domain set on my local DNS? How about SSL is it possible and/or necessary?
I did saw You could also use Tailscale and use their internal signed certificates. Then you can access it both internally and remotly over Tailscale with SSL.
Personally I own a domain for years and just use it.
