Two-Factor Authentication

On Your Apple Account

System Settings > [Your Name] > Sign-In & Security > Two-Factor Authentication

This is critical. Your Apple Account controls iCloud, Find My, purchases, and more. With 2FA, even if someone guesses your password, they can't sign in without your trusted device.

On Other Accounts

For non-Apple accounts (Google, GitHub, banks), use:

• Built-in verification codes: Apple Passwords can generate 2FA codes
• Authenticator apps: Microsoft Authenticator, Authy, or Google Authenticator

Avoid SMS-based 2FA when possible. SIM swapping attacks can intercept text messages.
