Security Tips

Use at least 12 characters for sensitive accounts
Mix all four character types for maximum strength
Never reuse passwords across multiple accounts
Store them in a password manager, not your browser
Enable two-factor authentication wherever possible

How It Works

This generator uses window.crypto.getRandomValues() — a cryptographically secure random number generator built into modern browsers. Unlike Math.random(), this API draws entropy from the operating system, making the output virtually impossible for attackers to predict.

Each password is generated entirely in your browser. Nothing is sent to our servers, nothing is stored, and nothing is logged. You can verify this by inspecting the page source or watching network traffic in your browser's developer tools.

The entropy shown next to the strength meter is calculated as length × log₂(charset_size) — a measure of how many guesses an attacker would need in the worst case. Anything above 100 bits is considered uncrackable with current technology.
