Understanding Multi-Factor Authentication (MFA)
Overview
Description: Multi-Factor Authentication (MFA) adds an extra layer of protection to your online accounts by requiring more than one method of verification when logging in. Instead of relying only on a password (single-factor authentication), MFA combines two or more factors something you know, something you own, or something you are; to confirm your identity and keep your information secure.
Understanding the Types of Identity Claim Factors
- Something you own: This refers to a device or item in your possession such as your smartphone, hardware token, or smartwatch that can be used to verify your identity.
- Examples include receiving a verification code via text message, email, or authentication app (such as Microsoft Authenticator or Google Authenticator).
- You’ll be prompted to enter this code to complete the sign-in process.
- Something you know: This is information only you should know, such as a password, PIN, or security question answer.
- When prompted, you’ll enter this information to verify your identity.
- Something you are: This factor uses your unique biological traits like a fingerprint, facial recognition, or retina scan to verify who you are.
- Biometric authentication tools confirm that you’re physically the person attempting to access the account.
Why MFA Matters
Passwords alone are no longer enough to protect sensitive data. Cybercriminals can easily obtain or guess passwords through phishing, data breaches, or social engineering.
By adding MFA to your login process, you create a stronger barrier: even if your password is compromised, an attacker still needs your phone or biometric data to gain access.
