Two-Factor #Authentication (2FA) typically combines a password with a code, whereas Multi-Factor Authentication (MFA) adds more layers, such as biometrics (fingerprint/face) or hardware tokens. Read MFA vs 2FA: What's the difference https://windowspost.com/2fa-vs-mfa/
Key Differences Between 2FA and MFA
Number of Factors: 2FA limits authentication to two layers (e.g., password + OTP), while MFA can incorporate three or more (e.g., password + OTP + fingerprint).
Security Level: MFA generally provides superior security against sophisticated attacks because it relies on multiple independent factors.
Complexity & UX: 2FA offers a more streamlined user experience with fewer steps. MFA may cause more user friction due to additional login steps, but it enhances security.
Flexibility: MFA offers greater flexibility, allowing organizations to adopt adaptive, risk-based authentication, while 2FA is a fixed two-step process
2FA Example: Entering a password (knowledge) and a code texted to your phone (possession).
MFA Example: Entering a password, a code from an app, and using a biometric scan (fingerprint or face)
