What is Multi-Factor Authentication in Cybersecurity?
Multi-factor authentication requires users to prove their identity through two or more independent factors: something they know (password), something they have (security key or phone), or something they are (biometric). MFA blocks the vast majority of credential-stuffing and phishing attacks.
Why Multi-Factor Authentication Matters for Your Cybersecurity Career
MFA is the single most effective control against account takeover. Every cybersecurity professional should understand MFA methods, their relative strengths, and bypass techniques. SOC analysts triage MFA-related alerts, and penetration testers test for MFA bypass paths like SIM swapping and push fatigue.
