"Password123" is dead. In an era of constant data breaches and GPU-accelerated brute force attacks, you need a password that mathematically guarantees security.

The Strong Password Generator creates high-entropy strings locally on your device.

Length vs Complexity

Most people think substituting @ for a makes a password safe. It doesn't. Hackers have "substitution tables" that check for P@ssw0rd instantly.

Length is the most important factor. Every character you add exponentially increases the time it takes to crack.

  • 8 chars: Cracked in minutes.
  • 12 chars: Cracked in centuries.
  • 16 chars: Heat death of the universe.

The XKCD Method (Passphrases)

A random string like J8#kL2!m is hard to remember. A passphrase like correct-horse-battery-staple is easy to remember but actually harder for a computer to guess because of its length (28 characters).

Client-Side Security

This is crucial: We do not send your password to any server. It is generated using the window.crypto API in your browser. Even if the NSA was monitoring your network connection, they wouldn't see the password because it never leaves your RAM.

Features

  • Exclude Similar Characters: Avoids confusion between l (lowercase L), 1 (one), I (uppercase i), O (uppercase o), and 0 (zero).
  • Strict Mode: Ensures at least one number, one symbol, and one uppercase letter.
