Frequently Asked Questions
What is multi-factor authentication (MFA)?
MFA is an authentication method requiring two or more verification factors, such as something you know (password), something you have (token), and something you are (biometric).
How does MFA improve security?
By combining independent factors, MFA reduces the risk of unauthorized access if one factor is compromised, strengthening overall protection.
What are common MFA examples?
Examples include password plus SMS OTP, hardware tokens with PIN, smartphone push notifications, and biometric factors like fingerprint or face recognition.
