Anecdote: I'm the account manager for most family members. One day my sister was angry with me, removed me as the account manager, and some months later locked herself out of her account after having trashed her phone and forgot her password.
She sounds like a rational actor.
I like that they have this, it means if I ever go missing unexpectedly that there'll be someone who can access my last known location, and access to social media comms to understand why.
I just tried to set that up and got a page that says it’s not available for my account.
You must already be deceased to use this service.
Probably not available for business & education accounts. Maybe not available in all countries?
