The Password Security Hierarchy

BestPasskeys / FIDO2 Hardware Keys

Passwordless. Cryptographic proof. Phishing-immune. Use wherever available.

GreatPassword Manager + Authenticator 2FA

Unique random 20+ char passwords + TOTP codes. Current best practice for most accounts.

GoodPassword Manager + SMS 2FA

Better than no 2FA. Vulnerable to SIM swap but blocks most automated attacks.

WeakMemorized Unique Passwords

Better than reusing, but humans create predictable patterns. Limited to ~5-10 accounts.

TerribleReused Passwords Without 2FA

One breach exposes all accounts. This is how most account takeovers happen.

5-Minute Quick Wins

  1. 1. Install a password manager right now (setup guide)
  2. 2. Enable 2FA on your email (2FA setup guide)
  3. 3. Check haveibeenpwned.com for all your emails
  4. 4. Change any password flagged as breached or reused
  5. 5. Enable passkeys on Google, Apple, and Microsoft accounts

Password Mistakes to Stop Making

Stop: Using the same password everywhere

Instead: One unique password per account. Let your password manager handle it.

Stop: Password123! style patterns

Instead: Use random generated passwords (20+ chars) or 4-6 word passphrases.

Stop: Storing passwords in a spreadsheet

Instead: Use an encrypted password manager (Bitwarden is free).

Stop: Sharing passwords via Slack/email

Instead: Use password manager sharing or self-destructing encrypted links.

Stop: Ignoring breach notifications

Instead: Change the password immediately. Check for reuse. Enable 2FA.

Stop: Using security questions honestly

Instead: Treat security questions as extra passwords. Store fake answers in your password manager.
