For images I highly recommend Immich. It’s the Google Photos equivalent, and it works excellently.

I use SyncThing for documents, but photos from my phone go to Immich.

Nope, sonce your Keepass database is store locally, all you need is Syncthing, you won’t beleive how easy it is to use.

You don’t. KeePass databases can be easily shared totally offline.

However, it all depends on “how easy” you want the sync to happen…

There are many ways to “sync” KeePass databases, basically you just have to copy password database among the devices, which can be done totally offline.

• HARD - Manually copy the KeePass database to the devices
  • Can be accomplished via any Network connection or USB cable connection
• EASIER - Put the database on any file sharing service that’s available on your devices, and sync that
  • The file sharing service can be available on the internet (Google Drive, OneDrive, iCloud…), but it also works with any file sharing service that’s not connected to the internet (e.g.: local only Nextcloud server, or not even that, using Syncthing if that’s your thing…, which would not even require a local server)

So, I’ll just give one example.

If you have 2 devices:

• Linux PC
• Android Phone

You can use KeePassXC on the Linux PC, and KeePassDX on the Android Phone, and have a copy of your kdbx file (the encrypted database) on each device, manually copying the newer version whenever there are changes on them.

Issues that might happen: consistency between the files in case you make changes to both databases and forgot to sync manually previously. There’s no easy way to handle this currently afaik if you are doing manual syncs… I’d suggest maintaining one of the databases as “kinda read only”, not performing edits on it unless you can immediately copy it to the other one.

You can do the same thing above, but instead of manually copying the files among the devices you can use Syncthing… Or if you have a local Nextcloud server, you can use that to share the files, which is pretty easy to use to ensure consistency if you are using KeePassXC and KeePassDX, since if you open the database on Android using KeePassXC directly to the “file system” that links to the Nextcloud folder, it will always automatically retrieve the newest version to your device if there has been any change and if your local Nextcloud server is reachable, otherwise it just uses the local cache, and you will know it’s using the local cache and was not able to sync.

Hoe do you sync it? I’ve been meaning to make the switch to these for a long time now, but still not gotten around to it.

It works pretty well! I found in my one quick test that a pair of known points on a diagonal offer the best tracking. Definitely need to play with that feature again.

I get the thought, but your phone can also have a security breach at any moment, ESPECIALLY because normal user error is by far the weakest and most often exploited attack vector.

Bitwarden’s vaults are also encrypted with the option for even stronger argon2id encryption. Bitwarden themselves can’t access them or reset them. It is open source and most importantly, audited. KeypassXC has only had one audit ever. (Though that passed and I would also definitely recommend keypassXC, it is great software security-wise)

The database is stored, encrypted, once on their server and once to each device you sync to, so it is available locally.

Even if they had a security breach, by design the assailant couldn’t access your database any more than they could access your keypass database.

You can also self-host it which would bring it exactly to the level of keypassX variants as far as attack surface.

Not to mention with bitwarden, you will also only need one key. That is the whole point of a password manager.

“It is available locally and a lot better…” is simply untrue. They are both great options. Just whatever works best for the person. Bitwarden has a ton more QoL options and enterprise options, plus separate, shared password databases and such for families and companies. Again, just as secure.
