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?
Reverse proxy + LetsEncrypt + DuckDNS + DNS rewrite to point it at local IP is all you need. Works quite well for all my services.
I prefer Keepass as it is less faff as a password manager is too critical to host like this imo.
