Password Generator
Generate a random password using your browser's cryptographically secure random number generator. Nothing is sent anywhere — the password only ever exists on your screen.
Strength: Very strong
How randomness works here
This tool uses crypto.getRandomValues(), the Web Crypto API's cryptographically secure random number source — the same underlying randomness used for encryption keys — rather than Math.random(), which is not designed to be unpredictable enough for security purposes.
Why length matters more than complexity
Adding characters to a password increases its strength exponentially, while adding more character types (numbers, symbols) helps but has a smaller effect. A longer password using just letters and numbers is often stronger than a short one packed with symbols.
Frequently asked questions
Is it safe to generate passwords online?
This generator runs entirely in your browser using the Web Crypto API — the password is never transmitted anywhere or logged. That said, for maximum peace of mind with highly sensitive accounts, a dedicated offline password manager is a reasonable extra precaution.
Should I reuse a generated password across sites?
No — use a unique password for every account. A password manager makes this practical by remembering them for you, so you only need to recall one master password.
