Example Concept: Multi-factor authentication for remote employees typically involves combining something they know (password), something they have (a mobile device with an authenticator app or a hardware token), and optionally something they are (biometric verification). This layered security approach ensures that even if one factor is compromised, unauthorized access is still prevented. Implementing MFA can be done using solutions like Google Authenticator, Microsoft Authenticator, or hardware tokens like YubiKey, integrated with VPNs and cloud services to secure remote access.
