I have my vaultwarden running on a container on my home-lab server acessible only from Tailscale. The container itself is only accessible as its own node on my Tailscale private network and can’t be reached any other way (there are no inbound port forwards for the container itself, tailscale handles this)

My phone and laptop both use tailscale to access this and a few other containers I have set up similarly. I also have tailscale ACL rules to limit just “me” or whomever I want to allow to use it (family etc) also on my tailnet.

Backups are encrypted and stored locally as well as to AWS glacier.

I love it and it works great.
