OAuth 2.0 is a protocol that allows third-party applications to access user data without exposing user credentials. It's widely used for secure authentication and authorization in modern web services.

Key Concepts 📘

  • Authorization Code Flow: The most common OAuth 2.0 flow for web applications
  • Implicit Flow: Simplified flow for single-page apps (SPAs)
  • Client Credentials Flow: For server-to-server communication
  • Scopes: Define the level of access (e.g., read, write, profile)

Use Cases 📱

  • 📱 Mobile Apps: Use Authorization_Code_Flow for secure token exchange
  • 🌐 Web Services: Implement Implicit_Flow for front-end access
  • 💼 API Integrations: Leverage Client_Credentials_Flow for machine-to-machine interactions

How to Implement 🔧

  1. Register your application with the OAuth provider
  2. Redirect users to the authorization endpoint
  3. Exchange the authorization code for an access token
  4. Use the token to request protected resources
