🔐 Cyber Security 102: Mastering Two-Factor Authentication (2FA)
What is Two-factor Authentication? How do you implement it and why should you use it?
Most of us use the internet daily: checking emails, shopping online, managing bank accounts. That’s why securing your accounts is more than optional—it’s essential.
One of the simplest, most effective tools to protect yourself is: Multi-Factor Authentication (MFA).
In this guide, you'll learn what MFA is, how it works, and how to enable it on Google and Microsoft accounts—no tech degree required.
🔍 What Is Multi-Factor Authentication?
Think of your online accounts as treasure chests. Your password is the key—but what if someone steals it?
MFA adds a second lock. It requires two or more pieces of information to access your account:
🔑 Something you know – Your password
📱 Something you have – A code sent to your phone or generated by an app
🧬 Something you are – Biometrics (like your fingerprint or face ID)
🔐 How Does MFA Work?
Let’s say you’re logging into your email:
You enter your password
A unique code is sent to your phone
You input the code, and only then get access
Even if someone steals your password, they can’t log in without that second factor.
⚠️ Important: If you receive a login approval request you didn’t initiate—do not approve it. That’s likely a hacker trying to sneak in.
📱 Setting Up MFA: Google Authenticator
Want to secure your Gmail, Google Drive, or YouTube account? Follow these steps:

Choose Google Authenticator as your second verification method
Scan the QR code shown on your screen with the app
