🔐 What is Two-Factor Authentication (2FA) and Why It Matters

🔐 Introduction

Passwords are no longer enough to keep your accounts safe.

Hackers can guess, steal, or crack them easily — especially if you reuse them.

That’s why Two-Factor Authentication (2FA) is one of the best ways to secure your digital life.

Let’s explore what it is, how it works, and how to set it up.

✅ What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security method that requires two types of verification to log in:

1. Something you know → Your password

2. Something you have → A phone, app, or device

Even if someone steals your password, they can’t access your account without the second factor.

Here are the most popular types of 2FA used today:

1. 🔢 SMS Codes

After entering your password, you receive a one-time code via text message.

2. 📱 Authenticator Apps

Apps like Google Authenticator, Microsoft Authenticator, or Authy generate time-based codes every 30 seconds.

🔍 Why is 2FA So Important?

Even if your password is:

• Leaked in a data breach

• Reused on multiple sites

• Phished via a fake login page

2FA prevents hackers from logging in without your device or code.

🔒 2FA can block over 99% of account takeover attacks, according to Google.
