I honestly can't stand comments like these. Why is every technology discussion on Lemmy dominated by people congratulating themselves for using something 'better'? Most of the time without even being asked.
On principal I don't use cloud-based password management solutions like this, but Proton Pass does make it somewhat tempting, especially since I have a Proton Unlimited subscription anyways. KeepassXC + syncthing do well enough, but PAM integration would be kind of nice some days when I'm opening and closing my vault a ton.
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.
