CompTIA A+ Certification Core 2 (220-1102) - Multifactor Authentication (MFA)

The video tutorial explains multi-factor authentication (MFA) and its importance in enhancing security. It covers four types of MFA: 'something you know' (e.g., passwords), 'something you have' (e.g., SMS codes, authenticator apps), 'something you are' (e.g., biometrics like fingerprints and facial recognition), and 'somewhere you are' (e.g., GPS-based verification). The tutorial also highlights Windows 11's sign-in options, including facial recognition and fingerprint scanning, emphasizing the need for multiple authentication methods to protect systems and data.
