1. Two-Factor Authentication (2FA/MFA): Always use a dedicated authenticator app (e.g., Ente Auth or 1Password) or hardware YubiKey on all critical accountsβnever rely on SMS OTP.
2. Dedicated Password Manager: Zero password reuse. Enforce unique, 16+ character random passwords managed through 1Password or Bitwarden.
3. Systematic OS Security Updates: Apply operating system patches (macOS, Windows, iOS, Android) within 48 hours of release.
4. Full-Disk Encryption: Enable FileVault (macOS) or BitLocker (Windows) with your recovery key securely stored offline.
5. Automated VPN on Untrusted Networks: Never connect to public Wi-Fi (cafΓ©s, airports, hotels) without an active encrypted tunnel (NordVPN or Proton VPN).
6. 3-2-1 Backup Strategy: Keep 3 copies of your files across 2 different media types, with at least 1 offsite encrypted cloud backup (pCloud or Sync.com).
7. DNS-Level Tracker & Ad Blocking: Enable DNS-over-HTTPS / NextDNS or Threat Protection to block malware and tracking telemetry before it loads.
8. Inactive Session Auto-Lock: Configure your screen lock to activate automatically after 3 to 5 minutes of idle time.
9. Strict Email Attachment Hygiene: Never open unsolicited macro-enabled Office docs or compressed archives from unknown contacts.
10. Separate Work & Personal Profiles: Maintain distinct browser profiles and OS accounts to isolate client credentials and session cookies.
11. FIDO2 Passkey Adoption: Transition to FIDO2 passkeys for cryptographic, phishing-resistant authentication wherever supported.
12. Digital Footprint & Leak Audits: Periodically audit your setup for WebRTC, DNS, and browser fingerprint leaks using SafeStackPro’s free testing tools.
13. Anti-Theft & Remote Wipe: Keep Find My / Remote Device Management active with cryptographic wipe enabled in case of hardware theft.
14. App Permission Pruning: Revoke microphone, camera, and background location permissions from all non-essential applications.
15. Physical Emergency Recovery Kit: Print and seal an offline Emergency Kit with master passphrases and recovery codes in a tamper-evident safe location.
