  • Surprisingly, I thought the article was a reasonable summary of the actual paper. I think some people might think this was a poke at privacy on Apple, but it really focused on how hard it is to create accessible settings despite the enormous number of options.

    I have found that navigating the menus in Apple iOS is quite a bit easier than on my Android devices. Mac seems more difficult as the settings tend to be inside the individual apps and don’t surface as well through the search.

    The paper hammered home the point that Siri configurations were particularly hard, but they also mention that Siri data is end-to-end encrypted. I thought all those points were fair.

    I do believe settings need to be improved, but I have little faith they will ever be useful for 99% of users who will simply never change anything from the default. At this point I believe any meaningful improvements for the majority of users will come from useful defaults that include E2E encryption on basically all user data. I feel Apple is coming close with iCloud Advanced Data Protection that was introduced last year, but that needs to become a default. Maybe it cannot though—too many users will lose all their data and then the trade off of security to convenience will not be worthwhile.



  • I agree that decrypt/encrypt is bad—it is simply not E2EE. The solution would have to be a better method of public key distribution for ‘federated’ systems.

    While I don’t know anything specific about facebook messenger, E2EE doesn’t necessarily preclude what you suggest. A messaging service could store the entire chat history encrypted without decryption keys. When you get a new client you could restore the entire history in encrypted form onto your device. You would then use a recovery key you would possess to decrypt the message history on your end. At no time would the messaging service have the keys to decrypt. I’m not saying that is what facebook does.



  • If you enable advanced data protection apple cannot recover your account. You need your recovery keys or a designated recovery contact.

    The apple doc implies (to me) that a SIM swap only works after you authenticate on an apple device (e.g. using your password) even without advanced data protection. I have never tested that.

    You can use the long process (many days) to recover an account assuming you haven’t enabled advanced data protection. I’m okay with that as it is perfect for my grandparents (I had an older relative who got their account back through this method).

    I get that you could SIM swap to recover other accounts (not Apple) if they have SMS as a recovery method. That sucks and it really sucks for people who don’t get that an email or SMS recovery can be a giant hole in security.


  • The document you linked says it requires a combination of your apple account password plus an SMS text sent to a pre-registered phone number? Seems like a pretty good setup for most people. Also has the alternative of recovery contacts and recovery keys.

    It looks like turning on advanced protection would eliminate the SMS method but I am not 100% sure. Then you would need recovery keys or recovery contact.

    My biggest worry in these cases is not that I get locked out, but rather that Apple mangles my keychain. I have a USB CSV of my passwords in my bank safety deposit box. With passkey I am not sure of how I would get a similar backup.
