Just like they say in crypto "not your keys, not your crypto" - it applies here too. Not your storage, not your passwords.
KeePass on an airgapped box, or an encrypted hardware password manager with no network interfaces is best, though frankly, I'd even be more comfortable writing down passwords on paper (at home) than I would be storing them on someone else's server.
I say all this as a big tech red teamer, or, someone who breaches other people's servers for a living.
