I have vaultwarden on my home server and I usually visit it through it’s Webinterface because the bitwarden addon for my browser breaks all the time with my vaultwarden instance.
I also have tailscale and a Headscale server so access should be VPN level secure.
I’m gonna be honest, it’s quite inconvenient sometimes but it’s an ok working setup.
The addon issue gives me the most headaches because it means I have to login like 10 times into the web ui and then search through the passwords every time I am building stuff on my servers.
I checked whether I can access the data on my disk with master password and I can, so I just setup periodical disk backups. Good enough for me, idk if that’s what you mean with emergency access though.
