> Maybe an option to 'lock' the account to changes, that can only be unlocked by the user when logged in, or by visiting a store? AT&T sorta offers this - there's an enhanced security option that lets you provide a password or PIN if you want to make account changes. This is allowed in lieu of ID. My AT&T account is technically still tied to my father-in-law, because my wife and I took it over over a decade ago, when we were still in college. They no longer have AT&T phones and I consider it my account, but whenever I visit a store I have to provide the password before I can upgrade my phone or change the service plan. To move the account into my name would require me and my FIL to visit a store together, which is inconvenient enough that we've not bothered.
