Generate Secure Passwords Locally — Without Internet
BigWow's Secure Password Generator uses Crypto.getRandomValues() — the browser's cryptographically secure random number generator — to create passwords. This means the randomness is generated locally on your device and the result is never sent to any server, API, or analytics pipeline.
Uses CSPRNG (Crypto.getRandomValues) — not Math.random().
0 API calls made during password generation.
Supports lengths from 8 to 128 characters with all character classes.
Frequently Asked Questions
Is a browser-based password generator truly secure?
Yes, when it uses Crypto.getRandomValues(). This API provides cryptographically secure random bytes from your OS's entropy pool. BigWow uses this API directly.
Does this generator send my passwords anywhere?
No. Password generation is pure JavaScript running in your browser tab. No network requests are made at any point during generation or display.
