Yeah, what I meant is that without a connection to the database, wouldn't I be SOL? Many of the passwords to access my NAS rely on my password manager to be available at all times.
Or does a cached version on mobile keep running even without the server?
(2nd concern is knowing that I've actually set it up to be secure... synology NAS's are always a target for hackers, and they come in waves of hundreds of attempts at a time some days.)
Yes, there's a cached version on your device. I never opened my server to the internet, just let it sync when on wifi. I used the vaultwarden docker container.
