Features Overview

Cryptographic Security

Uses the browser's native Web Crypto API (crypto.getRandomValues) rather than insecure pseudo-random algorithms.

Dynamic Entropy Meter

Calculates bit-entropy dynamically ($E = L \cdot \log_2(N)$) to gauge true strength against brute-force attacks.

Flexible Length Control

Includes both an intuitive visual range slider and a precise number input supporting lengths from 4 to 2048 characters.

Smart Exclusion Filters

Easily filter out lookalike characters (i, l, 1, O, 0) and ambiguous brackets or symbols for error-free typing.

Instant One-Click Copy

Quickly copy passwords with visual clipboard feedback and automatic fallback support for restricted browser contexts.

Zero-Server Privacy

100% client-side generation. No data or passwords ever touch a remote server or network connection.
