Simple Authentication implementation for ASP.NET Core.

  • Basic Authentication Scheme
  • API Key Custom Authentication Scheme


Download the package from NuGet:

Install-Package JN.Authentication


First, you must add one (or both) authentication scheme to the application pipeline:

public void ConfigureServices(IServiceCollection services)
    // Basic authentication 
      .AddBasic(options =>
          options.Realm = "api";
          options.LogInformation = true; //optional, default is false;
          options.HttpPostMethodOnly = false;
          options.HeaderEncoding = Encoding.UTF8; //optional, default is UTF8;
          options.ValidateUser = ValidateUser;
          options.ChallengeResponse = ChallengeResponseBasic;

    // ApiKey authentication - using Scheme
      .AddApiKey(options =>
          options.LogInformation = true;
          options.HttpPostMethodOnly = false;
          options.AcceptsQueryString = true;
          options.HeaderName = "ApiKey";
          options.ValidateKey = ValidateApiKey;
          options.ChallengeResponse = ChallengeResponseApikey;

ValidateUser, ChallengeResponseBasic, ValidateApiKey and ChallengeResponseApikey are delegates used to validate access details (username/password or ApiKey). Example:

public static Task<ChallengeResult> ChallengeResponse(Exception ex)
    // your code here...

public static Task<ValidationResult> ValidateApiKey(string key)
    // your code here...

On your controllers add the Authorize atribute and choose the Authentication Scheme ("Basic" or "ApiKey")

[Authorize(AuthenticationSchemes = "Basic", Policy = "IsAdminPolicy")]

public class BasicAuthSchemeTestController : ControllerBase
   // Your code here


Both authentication schemes allows to:

  • LogInformation: log information using a logging provider
  • HttpPostMethodOnly: allows only POST requests

Basic allows to specify a Realm and HeaderEncoding.

ApiKey authentication allows to change the HeaderName (default is "ApiKey") and can also accept the key in the query string (AcceptsQueryString)
