But is it necessary for the next of kin to have access to the account (I.e. Usernames, passwords, 2fa, etc)? Don't these sorts of places have protocols for when contacted by family of the deceased?
It's not strictly necessary, but it would surely make it a hell of a lot easier than needing to faff around providing death certificates etc., at probably an already very difficult time for them, particularly for things like utilities accounts which ideally need to keep ticking over as smoothly as possible.
