Enable MFA

🧾 What is it?

2-step login (also called two-factor authentication, or 2FA) adds a second layer of security to your online accounts.

Instead of just using a password, you'll be asked for something else — like a code sent to your phone, an app-generated code, or a fingerprint. This means that even if someone knows your password, they still can't get in without the second step.

🚨 Why it matters

Passwords can be guessed, stolen, or leaked in data breaches. It happens more than you think. 2-step login makes that password alone useless to a scammer.

That’s why most major services now offer it — and why we strongly recommend turning it on.

🧠 Common real-world examples

• You enter your Gmail password → then a 6-digit code is sent to your phone
• You log into your bank → then confirm with a code from an app or SMS
• You open Facebook → then approve the login through a mobile notification

📱 Types of 2FA (ordered best to worst)

1. Biometrics: Fingerprint, Face ID
2. Authenticator App: Apps like Google Authenticator or Authy
3. SMS Code: A text sent to your phone
4. Email code: A code sent to your email

Always enable 2FA on your email account first as it’s often used to recover other accounts.
