To secure ASP.NET Core API endpoints with Auth0 JWT validation, configure the Auth0.AspNetCore.Authentication.Api package with your tenant domain and API audience in appsettings and Program.cs to enable automatic bearer token verification.

Enforce scope-based authorization in a .NET 8 minimal API by applying .RequireAuthorization() or [Authorize] attributes with configured authorization policies that validate specific JWT scopes issued by your Auth0 tenant.

Yes, Auth0.AspNetCore.Authentication.Api supports DPoP proof-of-possession binding for ASP.NET Core APIs, ensuring that presented access tokens are cryptographically bound to the client holding the corresponding DPoP key.

Yes, you can use this Skill to protect both controller-based APIs and minimal APIs in ASP.NET Core, as it provides configuration guidance and endpoint protection examples for both architectural styles in .NET 8+ projects.

Correct middleware ordering for Auth0 JWT bearer validation requires placing authentication and authorization middleware appropriately within the ASP.NET Core pipeline to ensure tokens are verified before endpoint execution and scope enforcement.

If your ASP.NET Core API returns 401 with a correct Auth0 JWT audience, verify your appsettings configuration matches the tenant domain exactly and that token testing requirements are met per the guided setup workflow.
