    * Crack-time assumes offline guessing at ~10 billion attempts per second. Actual risk depends on hashing, leaks and attacker resources.

    Password tips
    • Use 16+ characters for random passwords when sites allow it.
    • Enable all character types for maximum entropy.
    • Passphrases work well for master passwords — use 4+ words.
    • Store passwords in a password manager — never reuse them.
    • Strength analysis updates automatically in the panel beside the generator.

    Generate strong, random passwords instantly

    Reusing passwords or picking predictable ones is one of the fastest ways accounts get compromised. This free password generator creates cryptographically secure random passwords and passphrases right in your browser — with custom length, character types and one-click copy.

    Random password vs passphrase

    Random passwords mix uppercase, lowercase, numbers and symbols to maximize entropy in a short string — ideal for most website logins when you use a password manager. Passphrases join several random words, making them longer and often easier to remember — a great choice for master passwords when you pick enough words.

    How secure is this generator?

    Passwords are built with crypto.getRandomValues, the browser API for cryptographically secure random numbers — not predictable Math.random output. Every generation happens on your device; nothing is sent to a server. For random mode, the tool guarantees at least one character from each selected type before filling the rest.

    How long should my password be?

    Most experts recommend at least 12 characters, and 16 or more for important accounts. Longer passwords resist brute-force attacks exponentially better. After generating, the built-in password strength analysis beside the generator shows a score, entropy estimate and crack-time analysis. You can also use the standalone Password Strength Checker to test any password.

    Questions

    Frequently asked questions

    How do I generate a strong password?

    Set length to at least 12 characters, enable all character types and click Generate. Copy the result and store it in a password manager.

    Is this password generator secure?

    Yes. It uses crypto.getRandomValues for secure randomness and runs entirely in your browser. Passwords are never uploaded or stored.

    What is passphrase mode?

    Passphrase mode joins random words with a separator you choose. Use 4 or more words for strong, memorable passwords.

    Should I exclude ambiguous characters?

    Optionally. It removes characters that look alike (like 1 and l) — useful if you might type the password manually.

    Is the password generator free?

    Yes — 100% free with no sign-up or limits. Everything runs locally on your device.
