Definition:
Multi-Factor Authentication (MFA) is a security process that requires users to provide two or more verification factors to gain access to a system or account, enhancing security beyond just passwords.
Use Cases:
- Used in online banking, email services, and corporate systems to secure user accounts.
- Employed in cloud services and applications to prevent unauthorized access.

Questions and Answers:
- How does MFA enhance security?
MFA enhances security by requiring multiple forms of verification (e.g., password + a one-time code), making it harder for attackers to gain access even if they have a user's password.
- What are common methods of MFA?
Common methods include passwords, security tokens, SMS codes, and biometric verification like fingerprints or facial recognition.
- Why is MFA important for high-risk accounts?
MFA provides an additional layer of protection for accounts that hold sensitive data, reducing the risk of breaches caused by weak or compromised passwords.
