Integrating Kinde Auth with ASP.NET Core 8 Blazor Apps

This is an example of how to use Clinically.Kinde.Authentication to simplify integrating Kinde with Blazor apps.

See the repo for that library for more information on how to use it.

The following needs to be in your appSettings.json on the server:

{
  "Kinde": {
    "Authority": "<From Kinde>",
    "ClientId": "<From Kinde>",
    "ClientSecret": "<From Kinde>",
    "ManagementApiClientId": "<From Kinde>",
    "ManagementApiClientSecret": "<From Kinde>",
    "SignedOutRedirectUri": "https://localhost:5001/signout-callback-oidc",
  },
  "AppConfig": {
    "BaseUrl": "https://localhost:5001"
  }
}

Roles

You can use the standard Authorize attribute:

[Authorize(Roles = "Admin")]

Permissions

In order to add authorization policies for your Kinde permissions:

builder.Services
    .AddAuthorizationBuilder()
    .AddKindePermissionPolicies<Permissions>();

Then create a Permissions class that contains all the Kinde permissions you want to use:

public class Permissions
{
    public const string MyPermissionName = "myPermissionNameInKinde";
}

Then you can use the permissions in your controllers or Razor pages:

[Authorize(Policy = Permissions.MyPermissionName)]

Notes

You need to go to the Tokens section of your app, and enable the Roles and Email claims in the access token.
In order to access the management API (e.g. to add users programmatially etc), inject KindeManagementClient into your services. Note you will need a separate M2M app in Kinde for this, with access to the Management API.
You can also inject KindeUserManager instead of the standard UserManager to get access to Kinde-specific methods.
Inject BlazorUserAccessor to get access to the current user in your Blazor components.
