16 characters

Passwords are generated entirely on your device using the Web Crypto API. Nothing is stored or sent to our servers.

Why Strong Passwords Matter

Weak or reused passwords are one of the leading causes of data breaches. A random password combining uppercase, lowercase, numbers, and symbols is far harder to crack through brute-force or dictionary attacks. Use this generator every time you create a new account, and store the result in a trusted password manager.

How This Generator Works

This tool runs 100% in your browser using JavaScript and the Web Crypto API (crypto.getRandomValues), a cryptographically secure source of randomness. There are no server requests, no database, and your password never leaves your device.
