Episode 8 — Make MFA Make Sense: When to Require It and How It Fails

This episode focuses on multi-factor authentication (MFA) and why it is a high-value control for reducing account takeover risk, a concept that shows up frequently in entry-level security exams. You will learn what counts as a factor, what does not, and how “two-step” can still be weak if it relies on the same underlying factor. We will discuss common MFA methods—authenticator apps, push approvals, hardware tokens, SMS codes—and compare them in terms of phishing resistance, reliability, and user friction. You will also learn how MFA can fail operationally through fatigue attacks, social engineering, lost devices, backup codes stored badly, or poor enrollment processes. Real-world best practices will include strong enrollment identity proofing, recovery planning, and choosing MFA methods appropriate to the sensitivity of the system and the threat model.
