Introduction to Azure AD B2C

Azure Active Directory B2C (Azure AD B2C) is a cloud identity management solution for your consumer-facing web and mobile applications. It lets you customize and control how customers sign up, sign in, and manage their profiles when using your applications. Azure AD B2C integrates with social identity providers, including Facebook, Google, and LinkedIn, as well as with enterprise identity providers via OpenID Connect and SAML protocols.

Creating an Azure AD B2C Tenant

Before you can use Azure AD B2C, you need to create an Azure AD B2C tenant. Follow these steps:

1. Sign in to the Azure portal.

2. In the left-hand navigation pane, select Create a resource.

3. Search for Azure Active Directory B2C, and then select Create.

4. Follow the prompts to create a new Azure AD B2C tenant.

Registering an Application

To allow your application to interact with Azure AD B2C, you need to register it in the B2C tenant. Follow these steps:

1. In the Azure portal, navigate to your Azure AD B2C tenant.

2. Select App registrations, and then select New registration.

3. Enter a name for your application, and then specify the redirect URI.

4. Click Register to create the application.

Configuring User Flows

User flows define how users interact with your application during sign-up, sign-in, and profile management. Follow these steps to create a user flow:

1. In the Azure portal, navigate to your Azure AD B2C tenant.

2. Select User flows, and then select New user flow.

3. Choose the type of user flow you want to create (e.g., sign-up and sign-in).

4. Follow the prompts to configure the user flow, and then click Create.

Integrating Azure AD B2C with Your Application

To integrate Azure AD B2C with your application, you need to update your application's code to use the B2C tenant for authentication. Here's an example in C#:

using Microsoft.Identity.Client;
using System;
using System.Threading.Tasks;

class Program
{
    private static string _clientId = "your-client-id";
    private static string _authority = "https://your-tenant-name.b2clogin.com/tfp/your-tenant-name.onmicrosoft.com/B2C_1_signupsignin";
    private static string[] _scopes = new string[] { "openid", "profile" };

    static async Task Main(string[] args)
    {
        var app = PublicClientApplicationBuilder.Create(_clientId)
            .WithB2CAuthority(_authority)
            .Build();

        var result = await app.AcquireTokenInteractive(_scopes)
            .ExecuteAsync();

        Console.WriteLine($"Token: {result.AccessToken}");
    }
}

Testing the Integration

Once you have integrated Azure AD B2C with your application, you should test the integration to ensure that users can sign up, sign in, and manage their profiles as expected. Follow these steps:

1. Run your application.

2. Navigate to the sign-up or sign-in page.

3. Complete the sign-up or sign-in process using a test account.

4. Verify that the user is authenticated and can access the application's protected resources.
