For folks new to the KeePass ecosystem, it’s KeePassXC[0] now. The original KeePass is still developed as well, however KeePassXC is a cross-platform updated version.
1. I have a side screen that is merely 360 pixels in height. KeePassXC does not work fine on it. KeePass2 does.
2. KeePass2 remembers the names of custom fields added and allows picking from those for a new entry. KeePassXC does not.
There are a few decent Android and iOS apps that work well. I use Nextcloud and WebDAV for access.
Not a setup I can recommend to just anybody though.
The need to have an opinion on how you’d like to sync a file does, as you suggest, eliminate some portion of the population who need a fully baked answer in one step.
I used to use Google Drive, but now I use Syncthing, further reducing my exposure. Paired with Synctrain and KeePassium on iOS.
One tip: enable the atomic save option in settings to reduce the risk of weird cloud sync issues.
For syncing, I do it manually with rsync. Given the database is 1 file it's easy to move around. You can rsync / scp it over, use a USB cable, use cloud storage, etc..
I use a password manager in a "read many, write infrequently" way so I don't mind occasionally syncing it as needed.
I’m sure it works for many people to Dropbox their vault around anytime they want to access something and manually handle copies and sync. I’m not nearly so naive as to think that has any degree of success outside tech bubbled people.
But we are prioritizing “can’t” over “won’t” in terms of provider access to our credentials. That’s why these hack-related threads tend to draw folks who will remind you that other tradeoffs exist.
For a technical audience like HN, “can work out how to sync a file” is a decent assumption to make.
