@protonmail Hi! Could you please help me by clarifying exactly how this Proton Pass differs from e.g. KeePassXC synced over Syncthing, apart from the additional cost for Proton Pass?
From what I can see, it seems to only be the e-mail address auto-generation, but since I have a private DNS-domain, with catch-all e-mail, that does not apply for me.

I have several times now gone through the details of Proton Pass thinking you must have launched it for some good reason because that's my experience with your projects so far, but I don't see it for this one.
Thank you!

@b9AcE There are multiple differences. For example, Proton Pass allows you to easily create unique alias email addresses upon signups, and it has an integrated 2FA authenticator: https://proton.me/pass.

However, at the end of the day, it all depends on your use case. We recommend that you check out our Reddit community (r/ProtonPass) to read other users' experiences and see whether Proton Pass fits your particular needs.

@protonmail
KeyPassXC also has integrated 2FA and as I described the e-mail address auto-generation does not benefit me, so it seems to me the answer is none, in my use case.
Everything can't be for everyone. ;-)

Thanks for the reply and clarification!
