How to Enable 2FA on All Your Socials (Step-by-Step)
Why You Need This NOW
If a hacker guesses your password, 2FA (Two-Factor Authentication) is the only thing stopping them from taking over your life. It adds a second "lock" that requires your phone.
The Hierarchy of 2FA
Not all 2FA is created equal. Here is the ranking from worst to best:
- SMS Text Message (Worst): Better than nothing, but vulnerable to "SIM Swapping" (hackers stealing your phone number).
- Authenticator App (Good): Apps like Google Authenticator or Raivo generate codes offline. Much safer.
- Hardware Key (Best): A physical key like a YubiKey. Unphishable.
Detailed Guides
1. WhatsApp (Crucial!)
If hacked, scammers will message your family asking for money instantly.
- Go to Settings > Account.
- Tap Two-step verification.
- Turn it on and create a 6-digit PIN.
- Important: Add an email address to reset the PIN if you forget it.
2. Instagram & Facebook
- Go to Settings > Accounts Center (Meta).
- Select Password and security > Two-factor authentication.
- Select your account.
- Choose Authentication app (Recommended) over SMS.
3. TikTok
- Profile > Menu (3 lines) > Settings and privacy.
- Tap Security > 2-step verification.
- Select at least two methods (e.g., SMS and Email, or Password and SMS).
Don't Get Locked Out: When you set up 2FA, the service will usually show you "Backup Codes" or "Recovery Codes". PRINT THESE OUT or save them in a password manager. If you lose your phone, these are the only way back in.
Why Authenticator Apps are Better
SMS messages travel over the cellular network, which is surprisingly insecure. An Authenticator App generates codes directly on your device using a mathematical formula and the current time. It works even in Airplane Mode!
