How secure is the random number generation?

We use the browser’s native window.crypto.getRandomValues() CSPRNG, which meets NIST SP 800-90A cryptographic standards.

Are generated passwords transmitted over the internet?

Never. Passwords are generated strictly inside your browser sandbox and are never sent over any network or logged anywhere.

What is Shannon Entropy in passwords?

Entropy measures the randomness and unpredictability of a password in bits. Passwords with 80+ bits of entropy are virtually uncrackable.

Entropy Strength: 112 Bits

Brute-Force Estimate: Centuries+

Randomness Source: Browser CSPRNG (Web Crypto)

What Makes a Password Truly Uncrackable?

Modern graphics card clusters (GPUs) can test over 100 billion SHA-256 hashes per second. An 8-character password consisting of only numbers or lowercase letters can be cracked in under a minute. However, increasing the length to 16+ characters with diverse character pools or using a 4-word Diceware passphrase raises the required attempts to $2^{90}+$ combinations, rendering brute-force attacks mathematically impossible within the lifespan of the universe.
