Why Cryptographic Randomness Matters

Many simple password generators rely on Math.random(), which is a pseudorandom algorithm whose internal state can be predicted. Our Password Generator uses window.crypto.getRandomValues() to fetch high-entropy random bytes from your operating system kernel.

Frequently Asked Questions

Are generated passwords saved or logged anywhere?
No. Password generation occurs 100% locally inside your web browser memory. No passwords ever leave your device.

What is a good password length?
For optimal security against brute-force attacks, we recommend a length of at least 16 characters with uppercase, lowercase, numbers, and symbols (providing over 80 bits of entropy).
