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.
