I use KeePassXC because I really only use one device. I imagine it would be challenging to rsync the database around if I needed my passwords on more machines. It’s probably fine if you’re deliberate enough, but I don’t think it would take long before I’d lose a password by editing an outdated version of the repository and overwriting the main copy.
I like the simple architecture of Pass, and it would indeed lend itself well to a Git repository, but I don’t like that service names are visible on the filesystem. pass-tomb might mitigate this somewhat but it seems messy and I don’t know if it would work with Git without compromising the security of the tomb.
What’s so good about Bitwarden? Everyone seems to love it. I like that it can be self-hosted. I certainly wouldn’t want a third party in control of my password database.
