SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Professional guidance for designing and validating secure authentication and authorization across web, mobile, and API systems. It covers identity flows, credential and token lifecycle, session/JWT/OAuth/OIDC/API-key patterns, and policy enforcement models (RBAC/ABAC/ReBAC).

Core Features & Use Cases

  • Guides architecture decisions for authentication and authorization across web, mobile, and API surfaces.
  • Covers token lifecycles, protocol choices (OAuth/OIDC, JWT, SAML, API keys, mTLS), and policy models (RBAC/ABAC/ReBAC).
  • Supports threat modeling and integration with related skills like security-pro, nestjs-pro, nextjs-pro, postgresql-pro, and testing-pro.

Quick Start

Ask me to design a secure authentication and authorization architecture for a multi-platform system, including token workflows and policy enforcement.

FAQPage Schema
How do I design a secure authentication and authorization architecture for web and mobile APIs?

Designing secure authentication and authorization for web and mobile APIs requires selecting appropriate identity flows, hardening token lifecycles, and enforcing server-side policies using protocols like OAuth, OIDC, and JWT to prevent unauthorized access.

What is the best way to choose between RBAC, ABAC, and ReBAC for policy enforcement?

Choosing between RBAC, ABAC, and ReBAC depends on your access control complexity: RBAC handles role-based permissions, ABAC evaluates attribute-driven policies, and ReBAC models relationship-based access for complex authorization architectures.

How do I harden JWT and OAuth token lifecycles to prevent security threats?

Harden JWT and OAuth token lifecycles by implementing proper method selection, server-side enforcement, and MFA considerations, ensuring secure token generation, validation, and revocation across your authentication system to mitigate threat modeling risks.

Can I use mTLS and API keys for authentication across multi-platform systems?

Yes, mTLS and API keys are valid authentication patterns for multi-platform systems, often integrated alongside SAML and OAuth/OIDC to secure web, mobile, and API surfaces through method selection and server-side enforcement.

When do I need OAuth and OIDC instead of basic API keys for system authentication?

You need OAuth and OIDC instead of basic API keys when designing decentralized authentication architectures that require delegated access, identity verification, and complex token lifecycle management across web and mobile platforms.

What are the limitations of using SAML for modern API authentication architectures?

SAML limitations in modern API authentication architectures include heavier XML payloads and reduced suitability for mobile platforms compared to JWT and OAuth/OIDC, making it better suited for enterprise web identity flows rather than lightweight API token systems.
