Why use 20 characters?

Extra length, extra margin

Twenty characters add a large safety margin over the common 12–16 character baseline. Pair this page with our 16 character generator or passphrase generator depending on the account.

Character Variety

Using a mix of uppercase, lowercase, numbers, and symbols dramatically increases password strength. Each character type expands the possible combinations hackers must try.

  • Lowercase only: 26 possible characters per position
  • Mixed case: 52 possible characters per position
  • All types: 95+ possible characters per position

True Randomness

Human-created passwords follow predictable patterns. Our strong password generator uses cryptographically secure pseudo-random number generation (CSPRNG) to create truly unpredictable passwords that cannot be guessed.

Tips for Maximum Password Strength

Use Unique Passwords

Never reuse passwords across different accounts. If one is compromised, others remain safe.

Use a Password Manager

Store your strong passwords securely. You only need to remember one master password.

Enable 2FA

Add two-factor authentication wherever possible for an extra layer of security.

Change After Breaches

Immediately change passwords for any accounts involved in data breaches.
