How do you handle your passwords?
I rely on Bitwarden (slooowly migrating from... a spreadsheet...) and am thinking of keeping a master backup to be SyncThing-synchronized across all my devices, but I'm not sure of how to secure the SyncThing-synchronized files' local access if any one of my Windows or Android units got stolen and somehow cracked into or something. I'm curious about how others handle theirs. Thanks in advance for sharing!
For years I've been using KeepassXC on desktop and Keepass2Android on mobile. Rather than sync the kdbx file between my devices, I have each device access it through the network. Either via sftp, smb, or nfs, but regardless I need to connect to my home's VPN to access it when away from home since I don't directly expose those things to the outside world.
I used to also keep a second copy of the website-tied passwords in Firefox Sync, but recently tried migrating that to Proton Pass because I thought the PIN feature might help, then ultimately decided to move away from that too and start using the KeepassXC-Browser plugin instead. I considered Bitwarden too but haven't tried it out yet, was somewhat deterred by seeing people say its UI seems very outdated.
It didn't look outdated to me, but is kind of weird and hard to get used to, though I eventually did. I don't know how to make an export from Bitwarden to take into KeePassXC, though... I'll need to look into this. Perhaps it can't be done from the browser alone. Anyway, thanks for sharing.
If you only have login names and passwords you can export to JSON and then import to KDBX using KeePass (works best) or KeePassXC.
If you have attachments (key files, certificates, etc...) then you will learn Bitwarden is not that open as it advertises. You will need specific scripts to move your data...
Is syncing the .kbdx files using Syncthing unsafe?
Syncing files that you may open in both (or more) devices at the same time is unsafe with any service, but you can manage to avoid sync conflicts with KeePass if you do not open the same file at the same time or open the Android app in read-only mode. I've only had like 3-4 conflict files this year and they weren't important.
