Password generation and storage practices

Current guidance on password length, uniqueness, password managers, and local generation.

TPublished by THB Project

Password strength depends primarily on length, uniqueness, and resistance to guessing. Reuse and predictable patterns create material risk even when a password contains several character types.

Recommended controls

  • Length — use a long password or passphrase appropriate to the service requirements.
  • Uniqueness — assign a different password to every account.
  • Random generation — use a cryptographically secure generator for accounts managed through a password manager.
  • Multi-factor authentication — enable an additional authentication factor where available.

Generator and storage workflow

  1. Generate a value with the Password Generator.
  2. Store the value immediately in a reputable password manager.
  3. Confirm that the saved entry matches the intended account and domain.
  4. Avoid transmission through email, chat logs, or shared notes.

Strength indicators

Password-strength indicators are estimates and do not guarantee resistance to compromise. Active passwords should not be entered into untrusted password-checking websites.
