- Step 2: Toggle uppercase, lowercase, digits, symbols, or ambiguous-character exclusion to customize your pool.
- Step 3: Click Copy or select 5 or 10 bulk passwords while reviewing live entropy bits.
Afterward, you can adjust any setting, compare alternative options, or download and copy your result immediately. Similarly, mobile visitors get touch-friendly controls that fit cleanly on any screen without horizontal scrolling.
Shannon Entropy Formula & Web Crypto CSPRNG Selection
Shannon entropy calculates unpredictability in bits: E = L × log2(R). Here, L represents character length and R counts unique symbols in the active character set. For example, 16 characters across 94 printable ASCII symbols yield 16 × log2(94) ≈ 104.9 bits. In addition, window.crypto.getRandomValues() supplies unbiased hardware-grade randomness locally in your browser.
Because our Password Generator applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for auto password maker or hard to guess password workflows can test multiple scenarios side by side before finalizing their work.
