How to Create Strong Passwords Safely

Use length, uniqueness, password managers, and multifactor authentication instead of predictable substitutions.

A strong password should be long, unique to one account, and stored safely. Complexity symbols can help generated passwords, but predictable substitutions do not rescue a short or reused password.

Prioritize length and uniqueness

Current NIST guidance requires at least 15 characters for a password used as a single authentication factor and recommends allowing at least 64 characters. For individuals, the practical lesson is to use long, unique passwords or passphrases rather than memorizing small variations of one password.

Use a reputable password manager

A password manager can generate and store a different random password for every account. Protect the manager with a strong master passphrase and multifactor authentication.

Enable multifactor authentication

A password is not phishing-resistant by itself. Add a phishing-resistant factor where available, and securely retain recovery codes.

Avoid common patterns

  • Reused passwords
  • Names, birthdays, addresses, and public facts
  • Keyboard walks such as qwerty
  • Predictable substitutions such as P@ssw0rd
  • Adding the current year to an old password

Using the local generator

The UtilityTrove generator uses browser cryptographic randomness and does not intentionally save the output. Copy the result directly into a reputable password manager, then clear the page. Avoid generating secrets on an untrusted or shared device.
