I really enjoy Proton Pass (but I have a paid subscription so I have passmail aliasses as well). I've been going full passkeys recently, no issues yet.
Before this I used Vaultwarden, but I was always a bit afraid of the self-hosting (of something this critical), and I really didn't like how you share credentials in BitWarden (through organizations), Proton Pass is much more intuitive with just straight up sharing of credentials or sharing whole Vaults. You can also share through public 1-time visit, limited time valid-urls. I use that a lot when I set up people's accounts.
What I don't like is the tight coupling to Proton's services, Pass should have had it's own credentials. But if you're not a Proton user that doesn't matter (or perhaps it doesn't matter t you in any case.)
Im a happy Proton customer since a decade for their email and recently file storage service, but I’m concerned about having my passwords and my files and my emails in the same system. It’s risky to have so much in one company, if I lose my proton access for some reasons I’m out of everything
