Authentication & Authorization Implementation Patterns

Build secure, scalable authentication and authorization systems using industry-standard patterns and modern best practices.

Use this skill when

Implementing user authentication systems
Securing REST or GraphQL APIs
Adding OAuth2/social login or SSO
Designing session management or RBAC
Debugging authentication or authorization issues

Do not use this skill when

You only need UI copy or login page styling
The task is infrastructure-only without identity concerns
You cannot change auth policies or credential storage

Instructions

Define users, tenants, flows, and threat model constraints.
Choose auth strategy (session, JWT, OIDC) and token lifecycle.
Design authorization model and policy enforcement points.
Plan secrets storage, rotation, logging, and audit requirements.
If detailed examples are required, open
```
resources/implementation-playbook.md
```
.

Safety

Never log secrets, tokens, or credentials.
Enforce least privilege and secure storage for keys.
