Keepass is exactly that. Basically all the client side parts, and the database is a single encrypted file that you can sync however you want.

I've done basically this in the past by encrypting a text file with GPG. But a real password manager will integrate with your browser and helps prevent getting phished by verifying the domain before entering a password. It also syncs across all my devices, which my GPG file only worked well on my desktop.

It's the "stringing it all together" that could be problematic.

If you have multiple clients (desktop/cellphone) modifying the same entry (or even different entries in the same "database" ). You need something smart enough to gracefully handle this or atleast tell you about it.

I did the whole "syncing" KeePass and it was functional, but it also meant I needed to handle conflicts - which was annoying. I switched and really appreciate the whole "it just works" with self-hosted bitwarden.

That is the bare minimum of a password manager like Bitwarden.

I see it as it's easy to self host. But I'm not skilled nor rich enough to guarantee the availability of it. I don't want to be stuck on a holiday without my passwords because my server back home died from black out or what have you.

I pay for bitwarden and the proton mail package to keep the password management market a bit more competitive and it actually works out cheaper. It would be nice to have protons anonymous emails built in, but I can live with it.

But I might have to reconsider if Bitwarden is going a different direction that what I'm paying for.
