Phosphor generates strong, random passwords using the movements of your mouse or finger — not a predictable algorithm. The more you move, the more randomness is collected.
- COLLECT RANDOMNESS — Move your pointer around the glowing field. The THERMAL FLUX bar shows how much has been gathered.
- FORGE YOUR PASSWORD — Once the bar is full, click FORGE CIPHER to generate a password from your collected randomness.
- COPY AND CLEAR — Use the COPY button, then PURGE & RESET to wipe all trace data from memory.
// Your password is created entirely inside your browser. Nothing is stored on a server or sent anywhere.
TECHNICAL DETAIL
- Your pointer coordinates (x, y) and timestamps are sampled continuously into an entropy pool (
Uint8Array).
- The pool is digested using SHA-256 via the browser’s built-in
window.crypto.subtle API.
- The resulting hash bytes are mapped to your chosen character classes using modular arithmetic to construct the final cipher.
- All operations are performed locally. No external libraries or network requests are used at any point.
