Proton I generally trust because they have made it abundantly clear just what they will give over to authorities in the event of a court order. I would rather it be less but I also prefer that over “We have your back and will fight the CIA if need be” nonsense.

That said: Bitwarden is still the kind of this. And the big issue with a keepass you sync (which I used to do) is that you can’t really use that with yubikey style devices because it will get out of sync as far as the authentication codes go.
