Securing Blazor WebAssembly with Single Sign-On

Modern web applications require robust security, but implementing user authentication in client-side WebAssembly can be challenging. This text-based course guides you through securing your Blazor WebAssembly applications using industry-standard Single Sign-On (SSO) and OpenID Connect (OIDC). You will learn how to configure secure authentication flows designed specifically for public client architectures, ensuring your user data and application state remain safe without exposing sensitive backend secrets. What you'll learn: - Understand the core concepts of Single Sign-On (SSO), OAuth 2.0, and OpenID Connect (OIDC). - Configure Blazor WebAssembly applications to communicate securely with external identity providers. - Implement the Authorization Code Flow with PKCE to eliminate the need for client secrets in the browser. - Manage authentication state and conditionally render UI components based on user login status. - Handle user claims, access tokens, and logout flows safely within client-side code. - Apply modern security best practices to protect client-side tokens from common web vulnerabilities. The course starts with essential authentication terminology and architectural concepts before moving into practical configuration steps. You will read detailed code explanations, analyze security patterns, and complete written exercises to solidify your understanding. Designed for web developers new to identity management in Blazor, this course requires no prior experience with SSO or OIDC.
