Episode 89 — Multifactor Authentication — Knowledge, Possession, and Biometrics

Certified - CompTIA Server+ Audio Course

This episode explains multifactor authentication (MFA) and how combining factors—something you know, something you have, and something you are—enhances security. We review examples such as passwords plus hardware tokens, smart cards plus PINs, and biometric scans paired with one-time passwords. The discussion also covers how MFA mitigates risks from credential theft or phishing attacks.

We then connect MFA to both exam content and operational implementation, including selecting appropriate factor combinations for different risk levels and integrating MFA with directory services or VPNs. Troubleshooting examples include resolving synchronization issues with authenticator apps and ensuring fallback authentication methods maintain security. Mastering MFA concepts ensures candidates can strengthen authentication processes against a wide range of threats.
