A Beginner’s Guide to Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA) is a security measure that adds an extra layer of protection to your online accounts. Here’s a simple guide to understanding what it is, why it matters.

What is MFA?

MFA requires two or more independent credentials to verify your identity. Typically, this includes something you know (like a password), something you have (like a phone), or something you are (like a fingerprint). For example, after entering your password, you might receive a code on your phone to complete the login.

Why is MFA Crucial?

• Protects Against Password Theft: Even if someone steals your password, they can’t access your account without the second factor.
• Reduces Cyber Risks: Data breaches are common, but MFA can block unauthorized access in 99.9% of cases, according to Microsoft.
• Safeguards Sensitive Data: For banking or email accounts, MFA prevents financial loss or privacy breaches.
• Mandatory for Compliance: Many industries require MFA to meet security standards.
