Having used KeePass for a few years, syncing via a self-hosted SFTP server, I can’t recommend it for most people.

• It’s too technical, especially if you want sync, but even if you don’t
• Apps on different platforms don’t quite agree with each other in all ways, making syncing a bit annoying (particularly: how to associate a login with multiple URLs)
• It can be hard to pick which app to use on each platform, other than Windows, because there’s no official/canonical best option (Mono has lots of drawbacks)

I’ve switched to Bitwarden and I’m sticking with it.
