User Authentication and Authorization with MSAL and Microsoft Graph

Building secure applications requires a solid grasp of how users sign in and how permissions are managed. Modern software development demands robust security protocols to protect sensitive user data and cloud resources from unauthorized access. This text-based course guides you through the foundational concepts of modern identity management, helping you transition from basic setups to secure, production-ready architectures. By reading through this comprehensive guide, you will gain a clear understanding of identity protocols and security best practices. You will learn how to configure secure login flows, manage granular permissions, and safely interact with cloud APIs using industry-standard mechanisms. What you'll learn: - Understand foundational authentication and authorization concepts, including OAuth 2.0, OpenID Connect, and Zero-Trust principles. - Configure user sign-in and token acquisition using the Microsoft Authentication Library (MSAL). - Implement secure delegated access to cloud resources using Microsoft Graph. - Generate and manage Shared Access Signatures (SAS) to grant limited-privilege access to storage resources. - Apply modern security practices, such as token validation, secure credential storage, and the authorization code flow with PKCE. This course begins with essential terminology and core identity security theory before moving into practical configuration patterns. Through structured text explanations and detailed code snippets, you will learn how to implement secure access control from scratch. Designed for beginner developers and security-focused IT professionals, this course requires no prior experience with identity platforms or advanced cryptography.
