How to Secure an ASP.NET Core Endpoint

Add the [Authorize] attribute.

Common authorization options:

  • [Authorize]
  • [Authorize(Roles = "Admin")]
  • [Authorize(Policy = "EmployeeOnly")]
  • [AllowAnonymous] for public endpoints
  • Configure authentication before using authorization

Protected endpoints require authenticated users before your action executes.

Public endpoints without [Authorize] are accessible without authentication.
