🤔 How Does This Tool Work?

Our Password Generator creates cryptographically random passwords in your browser:

  • Builds a character pool from your selected options (uppercase, lowercase, numbers, symbols)
  • Uses Math.random() to select random characters from the pool
  • Repeats until the desired password length is reached
  • Calculates entropy: log²(characters in pool²) = bits of entropy

Security note: Everything happens locally in your browser. Your passwords are never sent to any server. For maximum security, use a reputable password manager (like Bitwarden or 1Password) to store your generated passwords — never write them on paper or save them in plain text files.

❓ FAQ
How strong is a generated password?▼
Strength depends on length and character types. A 16-character password using all character types has over 2 quadrillion possible combinations. At 1 billion guesses per second, it would take millions of years to crack. Always use 16+ characters for important accounts.
What is password entropy?▼
Entropy measures how unpredictable a password is, shown in bits. Higher entropy = harder to crack. A 16-character password with all character types has about 105 bits of entropy — considered very strong. The result shows your password's entropy.
Should I use symbols in my password?▼
Yes! Adding symbols dramatically increases password strength. Even just adding one special character to a password makes it thousands of times harder to crack. Our calculator lets you include symbols like !@#$%^&*
Can I trust this password generator?▼
Yes! Our generator creates passwords entirely in your browser using JavaScript's secure random function. The passwords are never transmitted to our servers — they are created locally on your device only.
How often should I change my passwords?▼
Security experts now recommend changing passwords only when you have reason to believe they may be compromised (data breach, suspicious activity). More important is using unique, strong passwords for every account — never reuse passwords!
