Frequently Asked Questions
Is a browser-based password generator truly secure?
Yes, when it uses Crypto.getRandomValues() — the browser's cryptographically secure random number generator from your OS's entropy pool. BigWow uses this API, not Math.random().
Does BigWow store or transmit generated passwords?
No. Password generation is pure JavaScript in your browser tab. Zero network requests are made at any point.
What length should my password be?
NIST recommends a minimum of 12 characters. For high-value accounts, use 16–24 characters with mixed character types.
