Explanation
MFA (Multi-Factor Authentication) is a security measure that often uses an SMS or third-party application as a secondary method to access a system. MFA requires the user to provide two or more pieces of evidence to prove their identity, such as something they know (e.g., password), something they have (e.g., phone), or something they are (e.g., fingerprint). WPA2 (Wi-Fi Protected Access 2) is a security protocol for wireless networks that does not use SMS or third- party applications. AES (Advanced Encryption Standard) is a symmetric encryption algorithm that does not use SMS or third- party applications. RADIUS (Remote Authentication Dial-In User Service) is a network protocol that provides centralized authentication and authorization for remote access clients, but does not use SMS or third-party applications.
