My father passed many moons ago, and the family wanted access to his icloud account and they did not have the password. This was a huge struggle. Finally, after weeks, we were able to reset the password, but only because we had access to the email he used. In retrospect, perhaps it is a good thing that Apple restricts access like this for privacy and security. But in this digital age there should be other mechanisms in scenarios like this. What if i wake up from a coma, and forgot all my passwords and have not recorded them physically anywhere ?
