There are many benefits to using Azure B2C for businesses.

  • First, Azure B2C provides a scalable and reliable platform that can grow with a business.
  • Second, Azure B2C offers a wide range of features and tools that businesses can use to customize their experience.
  • Finally, Azure B2C is backed by Microsoft, which means businesses can trust in the quality and reliability of the service.

How Azure B2C Works

Azure B2C is a cloud-based identity management service that allows developers to add sign-in and registration capabilities to their applications easily. Azure B2C supports multiple identity providers, including social providers such as Facebook and LinkedIn and enterprise providers such as Active Directory.

Azure B2C is built on top of the Azure Active Directory (AD) Identity Management system, which provides the foundation for secure user authentication and authorization in Azure. Azure AD also powers other popular Microsoft services such as Office 365 and Dynamics CRM Online.

Using Azure B2C, developers can create custom policies that control how users authenticate and register for their applications. For example, a policy can be created that requires users to sign in with their social account first, allowing them to link their enterprise account if they wish. Azure B2C also supports “Cloud Apps”, which leverages Azure Active Directory, cloud storage and other Microsoft services to build enterprise web applications. Microsoft has made the source code for B2C available on GitHub. Azure B2C is based on OWIN and ASP.NET Identity.

Terminology around Azure B2C

  • User Flows in Azure B2C

When it comes to authenticating users in a web application, Azure B2C is a popular choice. But what is a user flow?

A user flow is simply a set of steps that a user takes to complete a task. In the context of Azure B2C, these steps might include registering for an account, logging in, and resetting a forgotten password. By defining these steps ahead of time, you can ensure that your users have a smooth experience using your web application.

  • Azure B2C Claims

When a user signs in to your application, Azure B2C issues a signed JWT (JSON Web Token) that contains claims about the user. These claims are specific to the user account and represent information about the user, such as their name, email address, and any other user attributes that were requested when configuring the sign-in policy. These claims are used by your application to authorize access to protected resources. The set of claims in a token is determined by the policies that are used when the user signs in.

You can add custom claims to the tokens that Azure B2C issues. For example, you could add a role claim to indicate the user’s role in your organization so that your application can use this claim to authorize access to protected resources.

Azure AD B2C uses two types of policies to control how users sign in: identity providers and sign-in policies.

  • Azure B2C User Attributes

User attributes in Azure B2C determine what information is collected about users during registration and login. There are around fifteen user attributes that can be selected, and each one has a specific purpose. For example, the first name, last name, and email address are all self-explanatory. However, other user attributes like job titles or preferred language can be used to segment users into different groups for marketing or customer service purposes.

User attributes can also be used to customize the experience a user has on your website or app. For example, if you know the city a user lives in, you can show them relevant content such as local events or news stories. Or if you know their favourite sports team, you can show them score updates and highlight merchandise for their team.

Azure B2C also allows for custom user attributes to be created.

  • Azure B2C Tokens

Azure B2C offers three different types of tokens: id_tokens, access_tokens, and refresh_tokens.

Identity tokens are used to verify the identity of the user. They contain information about the user, such as their name and email address. Access tokens are used to verify that the user is allowed to access a certain resource. They contain information about the user’s permission on a certain resource.

When you create an authorization server, you must specify which type of tokens it handles and which values they have.

Access tokens are used to grant access to specific resources. They can be used to authenticate a user when requesting an API. The OAuth 2.0 specification is the most popular authorization framework for securing the communication between clients and resources, such as APIs. It allows users to share their own data without sharing their credentials.

Refresh tokens are used to renew access tokens. They can be used to get new access tokens without re-authenticating the user. For this to work, the user must have a refresh token and an access token. The refresh token is used to get a new access token. After obtaining a new access token, it can be used for as long as it remains valid.

  • Azure B2C Identity Providers

There are a variety of identity providers that can be used with Azure B2C. Social media providers such as Facebook, Google, and Microsoft are the most common identity providers. Other common identity providers include Active Directory, LDAP, and SAML.

Azure B2C supports a wide variety of identity providers to choose the best one for your needs. Social media providers are the most common choice for many users because they are easy to use and provide a high level of security. However, if you have an existing directory such as Active Directory or LDAP, you can also use those. SAML is also supported for single sign-on scenarios.

No matter which provider you choose, Azure B2C makes it easy to integrate with your existing systems and provides high security and flexibility.

The Future of Azure B2C

Azure B2C is used by organizations to manage customer identities and access control for their applications. Azure B2C is built on the Azure Active Directory (AD) Identity Platform and includes all the features of Azure AD.

Azure B2C offers several benefits over other identity management solutions, including:

  • The ability to scale to millions of users with no performance degradation
  • A pay-as-you-go pricing model that doesn’t require an upfront investment
  • Built-in security and compliance features such as two-step verification and password reset

Organizations that are looking for a scalable, cloud-based identity management solution should consider Azure B2C.
