What is Azure Active Directory B2C?

Azure Active Directory B2C (Azure AD B2C) is a cloud identity management service that enables you to customize and control how customers sign up, sign in, and manage their profiles when using your applications. It's commonly used for business-to-consumer (B2C) scenarios where you want to use custom branding and authentication flows without needing to build and maintain a complete identity management system yourself. It supports various identity providers, including social media accounts, enterprise directories, and custom identity providers.
