GraphQL API Authentication and Security for Beginners

Building a GraphQL API is exciting, but securing it requires a different approach than traditional REST endpoints. Because GraphQL uses a single gateway, managing user identity and access control requires a solid understanding of token-based authentication and secure session management. This course guides you through the core concepts of securing your GraphQL schema from the ground up. You will transition from understanding basic security principles to implementing robust authentication flows that protect sensitive data. Through clear, step-by-step written explanations, you will learn how to handle user registration, safely store credentials, and manage active sessions using modern industry practices. What you'll learn: - Understand the differences between REST and GraphQL security architectures - Implement secure password hashing and verification using modern cryptographic libraries - Configure JSON Web Tokens (JWT) for stateless user authentication - Set up secure, HTTP-only cookie-based sessions for enhanced web client security - Apply schema-level and resolver-level authorization checks to restrict data access - Implement rate limiting and depth limiting to protect your GraphQL endpoint from malicious queries The course starts with essential security terminology and the foundational concepts of authentication versus authorization. Next, you will explore step-by-step how to structure your GraphQL context to pass user information safely, manage tokens, and write secure resolvers. This course is designed for beginner-to-intermediate back-end developers and web engineers who are new to GraphQL security. No prior security experience is required, though a basic familiarity with GraphQL schemas and JavaScript or Node.js is helpful.
