MFA
MFA (Multi-Factor Authentication) is a security method that requires users to prove their identity in multiple ways before accessing systems or data. Think of it like having both a key and a fingerprint to enter a building, instead of just a password. It's widely used in businesses to protect sensitive information and prevent unauthorized access. You might also see it called "2FA" (Two-Factor Authentication), "Two-Step Verification," or "Multi-Step Authentication." It's becoming increasingly important in cybersecurity and is often a requirement in many modern business systems.

Example Interview Questions
Senior Level Questions
Q: How would you plan and implement an MFA solution for a large organization?
Expected Answer: Should discuss assessment of organization needs, choosing appropriate authentication methods, planning rollout phases, user training, and handling potential implementation challenges.
Q: What considerations would you make when selecting an MFA solution?
Expected Answer: Should mention user experience, security strength, cost, integration with existing systems, backup authentication methods, and compliance requirements.
Mid Level Questions
Q: What are different types of authentication factors and when would you use each?
Expected Answer: Should explain something you know (passwords), something you have (phone/token), and something you are (fingerprint/face), with practical examples of each.
Q: How would you handle MFA for remote workers?
Expected Answer: Should discuss mobile authentication apps, hardware tokens, backup methods, and considerations for different internet connectivity scenarios.
Junior Level Questions
Q: What is MFA and why is it important?
Expected Answer: Should explain basic concept of multiple verification steps and why single passwords aren't secure enough for modern security needs.
Q: What are common MFA methods used today?
Expected Answer: Should mention SMS codes, authenticator apps, hardware keys, and biometrics as common verification methods.
