Cryptographically random password generation with strength checking. 100% client-side — your passwords never leave your browser.
A 16-character password with only lowercase letters has more possible combinations than a 10-character password with all character types. Length is the most important factor in password security.
This generator uses the Web Cryptography API's crypto.getRandomValues() — the same cryptographic standard used in banking apps. This is genuinely random, unlike Math.random() which is predictable.
A 5-word passphrase like "correct-horse-battery-staple-lamp" is both memorable and extremely secure — over 60 bits of entropy. Random passwords are stronger per character but harder to remember without a password manager.
Every password generated on this page is created entirely in your browser using JavaScript. Nothing is sent to our servers. We have no record of what passwords you've generated. This is verifiable by checking your browser's network tab.
