golang-gin-auth — Authentication & Authorization

Add JWT-based authentication and role-based access control to a Gin API. This skill covers the patterns you need for secure APIs: JWT middleware, login handler, token lifecycle, and RBAC.

When to Use

• Adding JWT authentication to a Gin API
• Implementing login or registration endpoints
• Protecting routes with middleware
• Implementing role-based or permission-based access control (RBAC)
• Handling token refresh and revocation
• Getting the current user in any handler
