SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates common security vulnerabilities in authentication systems by providing a standardized, hardened approach to password hashing, session management, and OAuth integration.

Core Features & Use Cases

Secure Hashing: Enforces PBKDF2 with 100,000 iterations via Web Crypto API to prevent brute-force attacks.
Session Hardening: Provides a robust schema for session management including device and location tracking.
Use Case: Use this when building a new login system or auditing an existing one to ensure that password storage, token comparison, and session invalidation meet modern security standards.

Quick Start

Use the implement-auth skill to audit the current authentication implementation and verify compliance with the PBKDF2 and session management standards.

FAQPage Schema

How do I implement secure password hashing using the Web Crypto API?▼

Secure password hashing enforces PBKDF2 with 100,000 iterations via the Web Crypto API to prevent brute-force attacks. This ensures login systems have hardened credential storage.

What is the best way to harden session management and enforce session lifecycle?▼

Session hardening requires a robust database schema for session management that includes device and location tracking. This enforces secure session lifecycle management and precise session invalidation.

How do I integrate OAuth into my existing login system?▼

OAuth integration is implemented alongside password hashing and session management to build complete login systems. It applies standardized authentication flows to account creation modules.

Can I use this approach to audit an existing authentication implementation?▼

Auditing an existing authentication implementation verifies compliance with PBKDF2 and session management standards. It checks that password storage, token comparison, and session invalidation meet modern security requirements.

Why does secure token comparison require constant-time comparison primitives?▼

Constant-time comparison primitives are required during token comparison in authentication flows to prevent timing attacks. Adhering to these primitives ensures secure session validation and lifecycle enforcement.

Do I need a specific database schema for authentication security metadata?▼

A specific database schema is required for security metadata to support session management. This schema includes fields for device and location tracking to maintain robust session lifecycle enforcement.
