Password Generator

This tool solves the need for strong, unique passwords across personal and organizational use cases. It targets individuals managing multiple accounts, IT security staff enforcing credential policies, and developers embedding generation logic into systems. It operates offline and does not contact external services, ensuring confidentiality.
Core operation builds a password from user-selected parameters: length, inclusion of lowercase, uppercase, digits, symbols, and optional exclusions for ambiguous characters. It uses a cryptographically secure RNG to sample from the pool until the requested length is reached, guaranteeing uniform distribution of character choices. The output is a password string that is not stored by the tool and can be copied or exported.
Differentiators include local generation without network calls, policy-aware options, optional seed-based reproducibility, batch generation, and straightforward export. Advanced users can explore repeatable options while maintaining security guarantees. The tool supports typical password policies and is suitable for onboarding, credential rotation, and security audits.
Use cases cover new account creation, periodic rotation programs, and compliance checks. Edge cases include incompatible constraints (e.g., no enabled character sets or unrealistic length) which yield explicit errors. Assumes ASCII-based character sets by default and excludes locale-dependent characters unless explicitly configured. The design emphasizes immediate, verifiable results and safe, ephemeral handling of generated data.
