Facebook now allows you to designate a “legacy contact”. This is a person who will be able to take over the account in a limited capacity if the user dies.

  • If you do not designate a legacy contact, but name a digital heir in a legal will, Facebook will honor your wish.
  • If you do not do anything, your Facebook account will simply freeze.
