"Oh no! My family members can't use the rule Netflix account." The humble email forwarder:

If a user that shares the account with you logs on, Netflix will nag that they are not part of the household. You have to receive a code on the mail address linked to the Netflix account to still be able to watch. Now my mail provider supports running automatic actions on my inbox: so I set it to check if the sender is Netflix and if that is the case to forward the email to a list of predefined contacts.
