What does connect with Apple do?
I won't ever use Apple services because of the lock-in. I haven't checked but I doubt there's an Android app, Windows App, or Firefox extension for Apple Passwords.
It's exactly like the "Connect with Google" feature but also "private" according to them. I don't know if it's a marketing argument or what but unlike Google they generate an alias email that is similar to what Proton does but for free. There is a Windows App.
I don't know what connect with Google is either so that explanation is not helpful
Basically you go on Reddit (It is French on the image because I'm French), you click on "log in" and look at the connection options.
Oh, I get it. Like a single sign on (sso). Facebook and amazon and github do this too, but it depends on the site.
You can't send out emails using Apple's temporary email service whereas you can with Proton's.
I'm not sure why I'd store passwords with any external provider. I keep a local database synchronized between my computers and mobile phones, with a backup elsewhere.
Does Apple encryption encrypt it from Apple? I legitimately don't know the answer to this, but I doubt it. Proton can't see your data even if they wanted to.
