API Authentication Guide

Authentication is crucial for securing your API endpoints. Here's a quick overview of best practices and methods:

🛡️ Key Concepts

• Token-Based Auth: Use JWT or OAuth2 for stateless verification
• API Keys: Simple but effective for client-side identification
• OAuth2.0: Ideal for third-party access control
• Rate Limiting: Protect against abuse with IP-based restrictions

📌 Implementation Steps

1. Generate Secret Key

2. Set Up Authentication Middleware

   # Example: Flask authentication setup
   @app.route('/protected')
   @auth_required
   def protected_route():
       return "Authorized access"
   

3. Validate Tokens

   

🔒 Security Best Practices

• Always use HTTPS to encrypt data
• Rotate secrets periodically
• Monitor failed login attempts
• Implement IP whitelisting

❓ Common Issues

• Token expiration: Use exp claim in JWT
• CORS errors: Configure proper headers
• Rate limiting bypass: Add X-Forwarded-For validation
