📌 Why is 2FA necessary?

The password is no longer protected. Hackers can steal passwords.

2FA (Two-Factor Authentication) adds another step to your password that further helps keep your account secure.

👉 In this, you:
Type your password
Then enter the code received on your phone
And only then does your account open

✅ How to set up 2FA (step by step)
🔍 1️⃣ What is 2FA?
This security system has two steps:
First: Your password
Second: OTP code received on your phone or secure device

👉 Even if someone knows your password, they cannot log in without your phone or device.
🛠️ 2️⃣ Which method to choose for 2FA setup?
How it works Security level
📱 SMS OTP code arrives on mobile Medium

🧾 5️⃣ Keep Recovery Codes Safe
After turning on 2FA, most service providers give you backup codes.
👉 What to do:
Write those codes down on paper and keep them in a safe place
Don't keep them in your phone or email
Don't share them with others

🔄 6️⃣ What to do if you lose your phone?
Use a recovery code
Contact your service provider's Account Recovery
