Password Generator

This tool generates cryptographically strong random passwords by combining user-defined length with selectable character sets. It targets security-focused individuals, developers, and IT staff who must meet organizational or policy requirements for password complexity. Conceptually, the password is formed by selecting characters from an allowed pool, where the pool size is the sum of the active character sets. The entropy is approximately length × log2(pool_size), providing measurable strength that scales with both length and charset richness. Core features include: configurable length, optional inclusion of lowercase, uppercase, digits, and symbols, and optional exclusion of ambiguous characters to improve usability. The tool uses a cryptographically secure RNG when available (e.g., window.crypto in browsers) and maps random values to pool indices to avoid bias. Outputs a single password string of the exact requested length and does not persist the value after generation. Typical use cases include onboarding new accounts, rotating credentials, and policy-driven password changes. Unique value lies in its transparent, configurable entropy model and strong default security posture without storing credentials.
