How to use asp net core identity ui with custom authentication service instead s

Introduction

ASP.NET is a popular programming language used for building web . One of the key features of ASP.NET is its ability to handle user authentication and . In this article, we will explore how to use ASP.NET Core Identity UI with a custom authentication service instead of the default authentication service.

Custom Authentication Service

By default, ASP.NET Core Identity UI uses the -in authentication service provided by the framework. However, in some cases, you may want to use a custom authentication service that suits your specific requirements. To do this, you need to create a custom authentication service and configure ASP.NET Core Identity UI to use it.

Let's start by creating a custom authentication service class:


 class CustomAuthenticationService : IAuthenticationService
{
    // Implement the required methods for authentication
    // ...
}

In the above code, we have created a class CustomAuthenticationService that implements the IAuthenticationService interface. This interface provides the necessary methods for authentication, such as SignInAsync and SignOutAsync.

Configuring ASP.NET Core Identity UI

Once we have our custom authentication service, we need to configure ASP.NET Core Identity UI to use it. This can be done in the Startup.cs file of your ASP.NET Core application.

, let's add the necessary using statements:


using .AspNetCore.Identity;
using Microsoft.Extensions.DependencyInjection;

Next, let's configure the authentication service in the ConfigureServices method:


public void ConfigureServices(IServiceCollection services)
{
    // Add your custom authentication service
    services.AddScoped();

    // Configure ASP.NET Core Identity UI
    services.AddDefaultIdentity()
        .AddDefaultUI()
        .AddEntityFrameworkStores();
}

In the above code, we have used the AddScoped method to register our custom authentication service with the dependency injection container. We have also used the AddDefaultIdentity method to configure ASP.NET Core Identity UI with the default identity user and the AddDefaultUI method to enable the default UI components provided by ASP.NET Core Identity UI.

Conclusion

In this article, we have explored how to use ASP.NET Core Identity UI with a custom authentication service instead of the default authentication service. By creating a custom authentication service and configuring ASP.NET Core Identity UI to use it, you can customize the authentication process to suit your specific requirements.

to test your custom authentication service thoroughly to ensure it meets your security and functionality .
