Privacy-First Password Management Best Practices

The Password Problem

The average person has 100+ online accounts but uses only 3-4 unique passwords. Credential stuffing attacks exploit this reuse — when one service is breached, attackers try those credentials everywhere. The only effective defense is unique, complex passwords for every account, which requires a password manager.

Choosing a Password Manager

Look for zero-knowledge architecture — the service cannot access your passwords even if their servers are compromised. Key features: end-to-end encryption, cross-platform sync, secure sharing, breach monitoring, and TOTP authenticator built-in. Consider whether your data is stored locally, in their cloud, or self-hosted. Evaluate the master password recovery mechanism.

Master Password Strategy

Your master password is the single point of failure. Use a passphrase of 4-5 random words (at least 20 characters). Never reuse it anywhere. Consider writing it down and storing it in a physical safe — this protects against memory failure while remaining secure against digital threats. Enable biometric unlock for daily convenience while keeping the master password for critical operations.

Multi-Factor Authentication

Enable MFA on every account that supports it. Priority order: hardware security keys (FIDO2/WebAuthn) > authenticator apps (TOTP) > SMS codes. SMS-based 2FA is vulnerable to SIM swapping but still better than no MFA. Use your password manager's built-in TOTP generator for convenience, or a separate authenticator app for security-critical accounts.

Ongoing Maintenance

Regularly audit your password vault for weak, reused, or compromised passwords. Most password managers include a security dashboard showing these issues. When a service announces a breach, change that password immediately. Review and remove accounts you no longer use. Export your vault periodically as an encrypted backup stored separately from your primary vault.
