MFA or Multi-Factor Authentication is a security mechanism where users authenticate using two or more verification factors to gain access to a website or application. This multi-layered security method helps prevent unauthorized access by making it more difficult to gain access even if one type of credential has been compromised.
How MFA Works
The real MFA usually is made of two or more of these factors:
What You Know — something like a password, PIN code or the answer to a security question.
What You Have: This is something like a token, phone, or security key.
Something You Are: Biometric factor such as fingerprint, facial recognition, or voice recognition.
Benefits of MFA
Improved Protection: MFA provides improved protection than single-factor verification.
Lower Probability of Phishing: MFA could be a defense against phishing threats because, normally, attackers have only a single form of credential.
Enhanced Compliance: In many industries, organizations must utilize MFA to meet regulatory requirements and standards.
More User Trust: Users tend to feel more assured that their accounts are protected by good security.
Common MFA Methods
Time-based one-time password (TOTP) — Create a unique code that is valid for a short period (e.g., 30 seconds).
Push Notification — Delivers a notification to a reliable device, where the user must accept the login attempt.
SMS-Based Verification: Sends a verification code using a mobile phone.
Biometric Authentication Uses biometric of fingerprints, or facial recognition.
Security key: A physical device producing one-time codes associated with separate login attempts
Implementing MFA
For successful implementation of MFA, consider the following tip:
Use Strong Methods:Opt for a method combination that is both user-friendly and strong.
