Introduction to Azure AD B2C
In today's digital landscape, providing a seamless and secure identity experience for your customers is paramount. Whether you're building a new application or enhancing an existing one, managing customer identities efficiently can be a complex challenge. This is where Microsoft Azure Active Directory B2C (Azure AD B2C) shines.
Azure AD B2C is a cloud-based identity and access management service that helps you build a scalable, secure, and feature-rich customer-facing identity solution. It allows your customers to sign up, sign in, and manage their profiles using their preferred social accounts, corporate credentials, or local accounts.

Why Choose Azure AD B2C for Customer Identity?
Traditional identity solutions are often built for internal users, not for the vast and diverse needs of external customers. Azure AD B2C bridges this gap with a host of specialized features:
Key Features
- Scalability: Built on Azure's robust infrastructure, it can handle millions of customer identities.
- Customization: Brand your sign-up, sign-in, and profile management pages to match your application's look and feel.
- Social Identity Providers: Integrate seamlessly with popular social networks like Google, Facebook, and LinkedIn for easy sign-in.
- Local Accounts: Support for traditional email and password sign-up.
- Multi-Factor Authentication (MFA): Enhance security with customizable MFA options.
- User Flows and Custom Policies: Define and manage identity journeys with pre-built user flows or advanced custom policies for complete control.
- API Protection: Secure your APIs with OAuth 2.0 and OpenID Connect.
- Compliance: Helps meet global compliance standards like GDPR.
Core Concepts: User Flows vs. Custom Policies
Azure AD B2C offers two primary ways to define identity experiences:
User Flows
User flows are pre-built, configurable identity experiences. They are the easiest way to get started, allowing you to quickly set up common scenarios like sign-up, sign-in, profile editing, and password reset without writing complex code. You can customize branding, attributes collected, and the identity providers supported.
Custom Policies
For more advanced and granular control over user journeys, custom policies are the way to go. Written in XML, they provide maximum flexibility to design complex identity scenarios, integrate with custom systems, and enforce specific business logic. While more complex to implement, they offer unparalleled customization.
# Example: A simplified user flow configuration (conceptual)
{
"kind": "B2C",
"userFlows": [
{
"name": "B2C_1_SignupSignIn",
"identityProviders": ["google", "facebook", "local"],
"userAttributes": ["displayName", "givenName", "surname"],
"resetPassword": true,
"profileEdit": true
}
]
