Account Takeover Defense: Protect Email & Social Accounts

About this course

This course explains how email and social media accounts are really taken over and how to shut each path down. You learn why your email inbox is the reset hub for everything else, how credential stuffing replays passwords from old breaches, and how a stolen session cookie can skip MFA entirely. You see why SIM-swapping makes SMS codes the weakest second factor, how malicious OAuth apps keep access after a password change, and why passkeys resist phishing. Practical lessons cover password managers, recovery settings and backup codes, breach checks and login alerts, plus a clear checklist for responding to a takeover. Each lesson ends with a challenge on your own accounts and a quick quiz, followed by a final exam and certificate. Defensive and legal use only.
