Email and Online Accounts – Level 3: Locking Down After a Breach and Securing the Household

This builds on Levels 1 and 2. Level 1 taught the basics. Level 2 taught you how to spot takeover attempts. Level 3 goes further: what to do when a real breach may already be underway, and how to secure not just one account but the small household system around it.

What is new here: this level is about diagnosis, recovery, and prevention across connected accounts and devices – not just one login at a time.
