From what I can tell as both a Bitwarden user and Proton Unlimited subscriber as well, is that Proton Pass is very good, but offers no reason to switch to it from Bitwarden, other than wanting to centralize more stuff to your Proton account. I don’t like the idea of centralizing stuff to Proton, despite their products being FOSS and them respecting privacy and everything, just out of principle. To be clear, it’s a very well made password manager and looks awesome, it just doesn’t really offer anything that Bitwarden doesn’t, so therefore I’m not compelled to switch to it, because there is (in my eyes) only a downside of switching, being the centralization of more services controlled by a single company. I don’t think that’s too big of an issue though, and still am comfortable recommending Proton Pass to anyone who doesn’t use a password manager yet (or anyone who uses their browser as a password manager), just why would I switch to it from Bitwarden?

Same question, and my answer is to not rock the boat.

Bitwarden is already good, and they’ve earned my money.

It’s definitely not as feature rich, but so far, it seems to be really well made.
