Nah, still a great solution if you like. That was my solution for years until just about a month ago I switched to bitwarden because it seemed easier to protect with a yubikey. I’ve liked it so far.

I took the opportunity to export all my passwords from Firefox, chrome, and KeePass, then spent about a day cleaning the whole mess up and removing duplicates, THEN imported the csv into bitwarden. Still getting used to not using chrome/Firefox for auto filling and storing passwords, but I like that my passwords don’t feel so spread out across multiple browsers/dbs.

Nope, that’s a pretty secure password manager setup.

Do you encrypt it before syncing in Dropbox? Or just raw .kdbx and password (+ key)?

No sir, I did this for years. I used Kypass on my iPhone so I could use my passwords on my phone as well. I ended up switching to Bitwarden for easier 2FA implementation and granular password sharing rather than having to share my whole vault or manage a separated shared vault

KeepassXC + SyncThing in my case, to skip the middle man (Dropbox/Google drive)

It works but partitions can and will happen and a merge afterwards is non-trivial AFAIK.
