I don't know any (automated) way of doing that with Lastpass or Bitwarden (though I have only tried the free versions thus far).

The other consideration for me is that I like to maintain versioned backups of my KP DB, so not only do I have a local backup of the whole DB, but I can roll back to several versions ago if I realise there's an integrity problem with the DB. Maybe the difference is that both the cloud storage password and the database password would be required to access my KP DB, but only one set of credentials would be required to access my Lastpass account (for example)? I've seen suggestions that if Lastpass (et al) were hacked, the data would be useless as it's all encrypted - is it really as straightforward as that?

I know they keep a copy of my password database on the cloud, but then I do that anyway by having my KeePass database file on cloud storage. I know these solutions talk of end-to-end encryption as a way of ensuring security, and I think I understand that in principle, but don't know enough about it to assess how foolproof it really is. I have been trying both of those, and they are so much more convenient, but I do worry about how vulnerable they may be to attack. I am a long-standing KeePass user, but I find its browser integration and Android apps a bit ropey, and certainly harder work than a cloud-based solution such as Lastpass or Bitwarden.
