Proton Pass is an open source, end-to-end encrypted password manager app. Create and store passwords, email aliases, 2FA codes, and notes on all your devices
Just wish KeepassXC supported Bitwarden export. Tried that earlier this week and it was no good. So staying on Bitwarden. I did install Proton Pass and tried it out. It is not as intrusive as Bitwarden on Android for permissions. Staying on Bitwarden for now . . . I hate passwords . . .
Export was JSON, keypassXC supports CSV so converted to CSV but the import seemed scrambled. Just didn't work well. I see there is an issue on bitwarden import but isn't ready yet for keepassXC
Probably none, if you're fine with KeePass. Personally I don't want to use anything that's hosted on someone else's server. It's a bit more inconvenient to use the local files of KeePass only, but I'd rather feel a bit safer with that, even if by all account BitWarden/Proton Pass would be fine.
I like Bitwarden because it's reliable, secure, feature-rich, and incredibly reasonably priced. But also, if they ever do something that crosses the line, I can spin up a Vaultwarden on a VPS and move my vault in an hour or two.
It's the same reason I host a dumb blog on WordPress owned infrastructure. I support FOSS companies, and like the ejector button freedom.
