Strong Password Generator

Create hard-to-guess passwords with real cryptographic randomness. Pick the length and character types, see the strength, and copy — all in your browser, so the password is never transmitted.

Choose a length and which character types to include (lowercase, uppercase, numbers, symbols), and the tool generates a strong random password using the browser's crypto API. It shows a strength meter and one-click copy. The password is generated locally and never sent to any server.

  2. 2Choose which character types to include.
  3. 3Copy the generated password, or regenerate for a new one.

Why generate passwords locally

A password is only secure if no one else sees it. This generator uses your browser's cryptographic random number generator and creates the password entirely on your device — it's never sent to a server, logged, or stored.

For the strongest passwords, use at least 16 characters with a mix of all four character types, and a unique password for every account.

Frequently Asked Questions

Is the password sent anywhere?

No. It's generated in your browser using the Web Crypto API and never leaves your device — nothing is uploaded, logged, or stored.

How strong should my password be?

Aim for at least 16 characters with uppercase, lowercase, numbers, and symbols, and use a different password for every account.

Is this random enough to be secure?

Yes — it uses crypto.getRandomValues, the browser's cryptographically secure random source, not ordinary Math.random.
