Then the problem is: “You’re leaking your Apple ID to everyone in your contact list!” or more, depending on how exactly they’d plan to distribute Apple IDs to everybody else. The hash of the phone number thing is to provide the “contacts only” airdrop thing.
- snarf21 7y agoI'm missing what you are saying, sorry. If I know your email already, nothing is getting leaked. If I don't know your apple ID email, I have to brute force all combinations of email concatenated with your phone number to figure it out. If a stranger doesn't know either piece, they'd have to pre-image the entire space which is nigh impossible (all phone #s X all email addresses)
- wool_gather 7y agoYou're right, but they probably have/want to cover the case where you've given someone just your phone number (or just your email).
- Operyl 7y agoIt’s convenient to just have a phone number be the piece both sides know. It’s not as magical if you need to also give your AppleID to every single contact manually, and if you have some sort of Phone Number to AppleID lookup service it’d be abused just as badly is what I’m saying here.
