What you'll learn

  • Understand OAuth 2.0 roles and the differences between authentication and authorization frameworks
  • Learn the various OAuth 2.0 flows, including Resource Owner Password Credentials, Implicit, Client Credentials, and Authorization Code flows
  • Gain insights into advanced security topics like Authorization Code Injection and PKCE (Proof Key for Code Exchange)
  • Understand OIDC, the differences between access and ID tokens, and token types like JWT and opaque tokens
  • Apply best practices for using scopes, enhancing security, and selecting appropriate flows for different applications

Course content

5 sections • 13 lectures • 4h 14m total length

  • Introduction to OAuth 2.04:01

    Explains why plain username and password login is insecure and introduces OAuth 2.0 as a secure, flexible solution that enables access to applications without re-entering credentials and supports third-party consent.

  • Roles in OAuth 2.05:25

    Explore the four key roles in OAuth 2.0—resource owner, client, resource server, and authorization server—and how access and ID tokens enable secure resource access.

  • The Authentication and Authorization Framework8:57

    Explore the authentication and authorization framework in OAuth 2.0 and OpenID Connect, distinguishing resource owner, client, resource server, and authorization server, and tracing token exchange via authorization codes and consent.

Requirements

  • A basic understanding of web technologies and HTTP protocols
  • No advanced security knowledge is necessary, but having a basic understanding of APIs will be helpful.

Description
