Lecture Notes: Azure Active Directory B2C in Angular Applications

Introduction

• Presenter: Karthik from Learn Smart Coding
• Topic: Adding authentication and authorization in Angular applications using Azure Active Directory Business to Consumer (Azure AD B2C)

Overview of Azure AD B2C

• AD: Active Directory
• B2C: Business to Consumers
• Azure AD B2C: Provides identity as a service, allowing users to sign up and log in.
• Azure is responsible for hosting all necessary components.

Key Concepts

• Azure AD B2C is designed for consumer applications.
• Allows applications to access attributes like name, address, and more.
• Users can sign up/sign in with a local account or social media accounts (e.g., Twitter, Google, Facebook).
• Supports custom branding of the login experience.

Standards and Protocols

• Developed using industry standards: OpenID, OAuth, and SAML.
• Provides multi-factor authentication (MFA) and integration with third-party identity proofing companies.
• Strong logging and auditing capabilities.

Compatibility

• Works with:
  • Server-based applications: .NET, PHP, Ruby, Node.js
  • Single Page Applications (SPA): Angular
  • Mobile applications
• Uses OAuth2 authorization code flow to secure web services and APIs.

Limitations

• Not suitable for long-running applications without a user interface.
• Incompatible with API chains (one API calling another) or web service chains.
