Layer 1 — Apple Account hardening
Settings → Apple Account → Password & Security. Verify Two-Factor Authentication ON. Add Recovery Key (write down, store in safe). Add Recovery Contact (trusted family member). Add multiple trusted phone numbers. Apple Account is your master credential — protect it like financial.Layer 2 — Stolen Device Protection
Settings → Face ID & Passcode → Stolen Device Protection → ON. CRITICAL iOS 17.3+ feature. After enabling, sensitive actions require Face ID/biometric even if passcode known. Defeats restaurant/bar/subway shoulder-surfing. Most important security upgrade Apple shipped — buried in Settings.Layer 3 — Hardware Key (YubiKey)
Buy YubiKey 5C NFC ($80) + backup ($80). Settings → Apple Account → Password & Security → Add Security Keys. Register both keys. Apple Account now requires hardware key — phishing-resistant. Strongest possible authentication.Layer 4 — Find My always on
Settings → Apple Account → Find My iPhone → ON. Plus Send Last Location ON. Plus Find My Network ON. Theft recovery + crowd-sourced finding. Anti-stalking detection. Stolen Device Protection works with Find My.Layer 5 — Lockdown Mode (if high-threat)
Settings → Privacy & Security → Lockdown Mode. Enable if: journalist, activist, executive at high-value target, dissident. Disables: link previews, Web JavaScript JIT, message attachment types, profile installation. Reduces attack surface for state-sponsored attacks. NOT needed for most users.Layer 6 — Privacy posture
Settings → Privacy & Security → Tracking → 'Allow Apps to Request to Track' OFF. Settings → Privacy → Location → System Services → review. Settings → Privacy → Apple Advertising → Personalized Ads OFF. iCloud Private Relay ON (iCloud+ subscribers). Mail Privacy Protection verified ON.Layer 7 — Passwords + 2FA
Settings → Passwords. Use Apple Passwords app (iOS 18+) OR 1Password OR Bitwarden. NEVER reuse passwords. Enable passkeys where supported. 2FA via authenticator app or YubiKey for important accounts. SMS 2FA only when no other option.Layer 8 — backups + recovery
Daily iCloud backup (Settings → Apple Account → iCloud → iCloud Backup). Plus Mac Finder backup (encrypted) before major changes. Recovery Key printed + stored in safe. Recovery Contact set. Account recovery flow tested. Lost iPhone scenario rehearsed.Mail-In Repair Service
