How to Generate a Strong Password Online

Set your desired password length using the slider (4 to 128 characters), choose which character types to include, and click Generate. The password is created using your browser's built-in cryptographic random number generator (Web Crypto API), ensuring true randomness. You can also generate multiple passwords at once.

Why Use Our Password Generator?

Unlike most online password generators, ours runs entirely in your browser. Your passwords are never sent to any server — they're generated locally using the Web Crypto API (crypto.getRandomValues). It's free, requires no signup, and shows you the estimated entropy-based strength of your password in real time.

Frequently Asked Questions

Is this password generator secure? Yes. We use the Web Crypto API (crypto.getRandomValues) for cryptographically secure random number generation. Your passwords never leave your browser.

What does "exclude ambiguous" mean? It removes characters that look similar in many fonts: 0 (zero) vs O (letter), I (capital i) vs l (lowercase L) vs 1 (one), and | (pipe).

How long should my password be? We recommend at least 16 characters with mixed types for strong security. 20+ characters is excellent.
