@YeOldeStonecat, BitWarden was recommended to me by a friend of mine that works at NASA's Cleveland facility. It's used by NASA internally.
And I figured, if it's good enough for NASA, it's good enough for me!

But I still drug my feet for darned near two years. The product has evolved tremendously in that time, even the last six months we've seen huge improvements.
But yes, if you're going to use it in the cloud put a good password on it that is never used anywhere else. Enable two factor... I've got mine attached to Duo, for free, via the generic TOTP stuff. I bought a "family" organization in the cloud $11 / year, I have an account with access, my wife has an account with access, neither account cost me a thing. We both have access to all our stuff in that one huge vault. Access is again two factor limited, and logged. So if someone gets in there, yeah I'm screwed but it's as strong as I know how to make it.
My NASA buddy just self hosts the thing at home, so his mobile devices sync in changes when he's there, and it's simply not on the Internet. That's probably best, but for $11 / year, I was lazy.
