Free Strong Password Generator

They are generated with your browser's Web Crypto API (crypto.getRandomValues), the same cryptographically secure random source used for encryption keys — not the weaker Math.random(). Every generated password also includes at least one character from each type you select.

16 characters with all character types gives roughly 100 bits of entropy — far beyond what any current attacker can brute-force. Use 20+ for anything critical, and never reuse passwords across sites; a password manager makes that painless.

No. Generation happens entirely in your browser's memory. Nothing is transmitted, logged, or saved — refresh the page and the password is gone forever.

It removes characters that are easy to confuse when reading or typing a password by hand: 0 and O, 1, l and I. Useful for passwords someone might need to type from a screen or paper.
