Frequently Asked Questions

What makes a password cryptographically secure?

A secure password combines high length (16+ characters), diverse character sets (upper, lower, digits, symbols), and high entropy generated by cryptographic randomness.

How does this password generator produce true randomness?

It utilizes the browser's native `window.crypto.getRandomValues()` API, which draws entropy directly from the underlying operating system kernel.

What is the recommended minimum length for a secure password?

Security experts recommend at least 16 characters for general accounts and 20+ characters for master passwords and banking accounts.

Is my generated password transmitted over the internet?

No, never. All generation occurs 100% locally in your browser. Passwords are never sent across a network or saved to any server.

What are memorable passphrase passwords?

Passphrases combine 4 to 6 random dictionary words (e.g., 'correct-horse-battery-staple') for high entropy that is easy for humans to memorize.

How do symbols and numbers increase password entropy?

Adding symbols and numbers expands the possible character pool from 26 to 94 possible characters per position, making brute-force cracking exponentially slower.

Can I exclude ambiguous characters like (1, l, I, 0, O)?

Yes. You can toggle the 'Exclude Ambiguous Characters' option to prevent confusing look-alike letters when typing manually.

Why should I never reuse passwords across multiple websites?

If one service suffers a data breach, hackers use credential-stuffing bots to test that password across hundreds of other popular platforms.
