Welcome to the User Authentication sample guide. This documentation provides a clear overview of implementing authentication mechanisms in your application, including OAuth 2.0 and JWT integration examples.

Overview 📈

Authentication is critical for securing user data and ensuring only authorized users access specific resources. Here are common authentication methods:

  • OAuth 2.0: For third-party login integration
  • JWT (JSON Web Token): For stateless session management
  • Basic Auth: Simple username/password validation

For more technical details about OAuth 2.0, check our OAuth 2.0 Guide.

Implementation Steps ⚙️

  1. Set up an authentication server

  2. Implement token validation logic
    Use middleware to verify JWT signatures and check expiration times.

  3. Secure API endpoints
    Add authentication headers to all protected routes.

Example Code 📜

# OAuth 2.0 example (simplified)
def authenticate_user(token):
    if validate_token_signature(token):
        return "User authenticated successfully"
    else:
        return "Invalid token"

Common Issues ❓

  • Token expiration: Always set a reasonable expiration time (e.g., 1 hour)
  • Security risks: Use HTTPS for all communication
  • User session management: Avoid storing sensitive data in client-side cookies
