Hour 1: The phone becomes the front door to everything, and nobody can open it
In the first hour, families usually reach for the phone. They need contacts, banking apps, provider emails, subscriptions, passwords, authenticator apps, and messages from doctors, attorneys, or service providers.
Here is what most families do not know. Apple will not unlock a phone, even when shown a death certificate. Face ID disables automatically after 48 hours of inactivity. Ten wrong passcode attempts can wipe the entire device permanently. A family can be standing in a carrier store with the device in hand and still have no way to receive verification codes. No carrier, no Apple agent, and no bank has the authority to open that phone.
The problem is not just knowing one password. It is knowing the whole access chain.
