System Documentation
What problem does it solve?
Password storage has historically been mishandled, exposing users to credential theft when hashes are fast, salts are missing, or legacy schemes are used. This Skill provides guidance and concrete practices to select strong password hashing algorithms, implement proper salting, maintain secure storage, and detect breached credentials.
Core Features & Use Cases
- Algorithm selection guidance for Argon2id, bcrypt, scrypt, and PBKDF2, with recommended parameters.
- Salt requirements, storage guidelines, and per-password unique salts to prevent rainbow table attacks.
- Migration strategies for legacy hashes, breach-detection integration, and policy enforcement across services.
- Secure password reset flows, constant-time comparisons, and non-revealing error handling.
Quick Start
Review and implement a password storage strategy using Argon2id or bcrypt, set up per-user salts, enable breach-detection checks, and plan a migration path for existing hashes.
