KeepassXC
Mixed with syncthing to sync your database file across your devices and its chef’s kiss
My only complaint with KeePass is that if any corruption occurs, your passwords are borked. I use KeePass for non-critical accounts, like Lemmy, etc. I don’t trust myself or the sync enough for storing my bank or other identity passwords.
I have used KeePass for many, many years and have never run into this. Besides, I usually have a copy of the database on some other device so I’m not too worried
Syncthing means it and it’s backup lives on two laptops a desktop and my phone.
Beware that syncthing is a bad backup strategy as it will update to sync the broken file (or even file deletion). I advice to do some other sort of backup. Even a simple shell script that copies selected folders into selected location that you run from time to time is a better one.

I use rsync for that.

As does syncthing under the hood. The issue is with backing up an open database and getting an inconsistent state, but KeepassXC keeps it’s database closed except on update. I also tick the backup old before save setting in KeepassXC (the aforementioned ‘and it’s backup’) and use a versioning backup of the sync directory on the desktop with 3-2-1, so I am sanguine.

Syncthing can easily be set to retain the last n copies. And you only need one or two to protect against corruption because you aren’t editing a corrupted file. Likewise a lot of the KeepassX clients can snapshot periodically too. Been doing this for years with no issues over Linux/Win/iOS and Android.
