Password Generator

Create strong, random, secure passwords instantly — built on cryptographically secure randomness. Free, fast and private: passwords are generated on your device and never uploaded.

Private by design — passwords are generated locally with secure randomness and never uploaded.

How to generate a strong password

  1. Set the length with the slider — 16 or more characters is recommended.
  2. Tick the character sets you want: uppercase, lowercase, digits and symbols. Optionally exclude ambiguous look-alike characters.
  3. Click Generate, then Copy to use your new secure password.

Why use a secure password generator?

People reuse weak, guessable passwords — and that is how accounts get breached. A strong random password generator removes the human bias that makes passwords predictable, drawing each character from a cryptographically secure source so attackers cannot anticipate the result. The more length and character variety you allow, the more astronomically large the search space becomes, putting brute-force attacks out of reach. Because everything runs in your browser, your password is never transmitted or logged anywhere, so you can paste it straight into your password manager with confidence.

Frequently asked questions

Is this password generator free and private?
Yes — it is 100% free with no sign-up, and completely private. Passwords are generated in your browser with the cryptographically secure crypto.getRandomValues API; nothing is ever sent to or stored on a server.
What makes a password strong?
Strength comes from length and unpredictability. A long password (16+ characters) drawn from a large mix of uppercase, lowercase, digits and symbols has far more possible combinations, making it impractical to guess or brute-force.
Why use crypto.getRandomValues instead of Math.random?
Math.random is not cryptographically secure and can be predictable. crypto.getRandomValues uses the browser's secure random number generator, which is suitable for generating secret keys and passwords.
What does "exclude ambiguous characters" do?
It removes look-alike characters such as 0/O and 1/l/I so the password is easier to read and type without transcription errors — useful when you have to copy a password by hand.
