JavaScript Password Generator

Generates strong, configurable passwords for developers and security-conscious teams. It uses cryptographically secure randomness to assemble a password from user-selected character sets and length, ensuring policy-compliant credentials without manual guessing. Primary beneficiaries include software engineers provisioning services, DevOps engineers securing CI/CD pipelines, and database administrators rotating credentials. The tool provides an auditable password string, plus lightweight metadata such as estimated entropy and a strength label. Unique value lies in explicit entropy estimation, flexible exclusion rules, and export formats that fit scripts and config files, all without storing credentials.
How it works conceptually: the user selects length and which character groups to include. The generator builds a pool from the enabled sets, guarantees representation from each active group when possible, and shuffles the chosen characters with a cryptographically secure RNG. The result is a password that meets the requested policy while maximizing unpredictability. Outputs include the final password and optional metadata (entropy approximation, strength). Typical use cases include API keys, service accounts, database passwords, and ephemeral credentials for automated deployments. It does not manage storage, rotation scheduling, or policy enforcement.
Core value & features: Required inputs are length and a subset of character groups; optional features include exclude_chars, avoid_repeats, and multiple export formats. Outputs are a single password plus optional metadata suitable for auditing or integration in scripts. This is a generation utility, not a password manager or vault.
