So I have an admission here: I keep seeing HN stuff about these networked password managers and I don't quite understand the appeal. Is it because everybody else is swapping between several different computers, and you need the synchronization? I just have everything in KeepassXC, and the ciphertext is subject to the same kind of backup regime I use for other files, [edit: and also additionally] a copy kept on a USB…
Syncing was an utter disaster. Inevitably something would cause syncs to be delayed, and then there would be a conflict and one of our changes would be silently lost. We were constantly going to lookup a password we entered, and finding it was not there anymore, at which point I would have to dig through sync conflict backup files and manually reenter the passwords that were lost, or go through the password reset flow for the sites. It was a giant mess, and that was just with two desktops and a laptop. I was using btsync at the time but all the issues I encountered apply to any file based synchronization, like syncthing, nextcloud or dropbox. Performing whole database file synchronization is simply not the right approach for password safe.
I eventually switched over to self-hosted BitWarden with the browser plugin and it has been much smoother.
