À propos de Password Generator

Strong, unique passwords are still the single biggest defense against account takeover. Our free password generator builds cryptographically random passwords up to 64 characters long, with optional uppercase, lowercase, numbers and symbols. Everything runs in your browser using the Web Crypto API — your passwords never touch our server.

Comment l'utiliser

  1. Choose your desired password length using the slider (8–64 characters).
  2. Toggle character types: uppercase, lowercase, numbers, and symbols.
  3. Click Generate to create a cryptographically random password.
  4. Use the strength meter to make sure your password is strong enough.
  5. Copy the password to your clipboard with the copy button.

Formule et méthodologie

Password entropy = log2(N^L) where N = number of possible characters and L = password length. Higher entropy means stronger passwords. An 8-character password with all types has ~52 bits of entropy; 16 characters has ~104 bits.

Cas d'usage courants

  • Creating strong, unique passwords for every online account
  • Generating secure WiFi passwords for home or office networks
  • Building complex master passwords for password managers like 1Password or Bitwarden
  • Creating temporary passwords for new user accounts
  • Teaching password security best practices to teams or family members

Questions fréquentes

Aim for at least 12 characters with a mix of uppercase, lowercase, numbers and symbols. Each additional character exponentially increases the time needed to crack the password. A 16-character password with all character types would take billions of years to brute force with current technology.
Yes. Our generator uses the Web Crypto API's cryptographically secure random number generator — the same standard browsers use for TLS encryption. This is far more secure than typical Math.random() based generators and is suitable for banking, email, and other sensitive accounts.
Absolutely. A password manager lets you use a unique, randomly generated password for every account without needing to memorize them. You only need to remember one strong master password. Recommended managers: 1Password, Bitwarden, and Apple iCloud Keychain.
