- Tokens provide temporary access to resources for limited periods
- System works across different domains using HTTP headers
- Advantages
- Enables cross-domain AJAX calls without cookies
- Provides stateless authentication without session store
- Supports CDN integration and mobile-ready functionality
- Offers decoupling from specific authentication schemes
- Eliminates CSRF protection through token-based approach
- Implementation Steps
- Install necessary OWIN packages in Visual Studio
- Create Startup.cs class for authentication
- Implement OAuthCustomTokenProvider and OAuthCustomRefreshTokenProvider
- Configure token expiration time in Startup.cs
- Test authentication using Postman with Bearer token
- Verification
- Create Web API controller with [Authorize] attribute
- Test token usage with POST requests
