Authentication models are central to IT security, and this episode covers them in detail for the CompTIA IT Fundamentals (ITF+) certification exam. You’ll learn the differences between single-factor authentication, multifactor authentication (MFA), and single sign-on (SSO). We’ll explain how each model works, where it’s most appropriate, and the trade-offs between security and convenience.

We’ll also explore real-world examples of MFA implementations, including combinations of passwords, smart cards, and biometrics. This knowledge prepares you to recommend the right authentication approach for a given situation, both in exam scenarios and professional practice. Produced by BareMetalCyber.com.
