Password Generator
Create a cryptographically strong random password instantly. Customize it, copy it, and use it.
How does this password generator work?
CyDuck's password generator uses crypto.getRandomValues() — the browser's built-in cryptographically secure random number generator. This is the same API used for SSL/TLS and other security-critical operations. It is fundamentally different from Math.random(), which is not suitable for security purposes.
Every generated password guarantees at least one character from each selected character type, then fills the remaining length with random pool characters, and finally shuffles the result using the Fisher-Yates algorithm to eliminate any positional bias.
Tips for using your new password
- Store it in a password manager (Bitwarden, 1Password, KeePass) — don't memorize it.
- Never reuse a password across multiple sites.
- Enable two-factor authentication (2FA) wherever possible — a strong password + 2FA is nearly unbreakable.
- Aim for at least 16 characters for regular accounts, 24+ for anything financial.
What does crack time mean?
Crack time is an estimate of how long it would take an attacker making 10 billion guesses per second to brute-force your password. Modern GPUs can reach this speed, so a password that takes a few seconds to crack online could fall in milliseconds to an offline attack. This is why length matters more than complexity.
Frequently Asked Questions
Is this password generator truly random?
crypto.getRandomValues(), which is the gold standard for browser-based randomness. No patterns, no seeds based on predictable values like the current time.
