Bu you would have 1:1000000 chances to get into someone elses phone. With 7 billion people in the world it's not so crazy.

For the encryption keys to transfer I think you would also have to allow the request from some other device which currently held them. The Secure Element would need to be upgraded to support "multi-tenancy". That's all assuming the feature works by building on the existing infrastructure. Ideally between your face and your iCloud password you could bring your "profile" to new hardware without having to touch an existing device. After the first time, just your face is enough.

- function_seven 9y agoRead the GP comment. This is talking about walking up to any random phone and having your own environment synced to it seamlessly. For that to work, the phone would have to know it’s you with basically perfect precision. So 1 in a million is not nearly good enough for that use case.
