CISA's four habits (multifactor, updates, think before you click, a password manager) only hold if someone in the house can recover the others. Shared streaming logins, one spouse's email as the family reset, and a router nobody else can log into are how a personal checklist fails as infrastructure.
Consumer security advice used to address a single adult and a single PC. Households now share streaming, shopping, school portals, and a router, while attacks still start with phishing and reused passwords. CISA's Shields Up guidance for families repeats four individual habits: multifactor authentication, software updates, skepticism toward links, and a password manager. Those habits become durable only when the household also has shared recovery: a family vault for truly shared logins, private vaults for everything else, a second person who can approve an account recovery, and a written way to reach the password manager if the organizer is unavailable. Fear-based 'lock it all down' messaging that nobody can operate is how people go back to a paper list on the fridge.
