When securing APIs, advanced authentication methods go beyond basic token-based systems. Here are key strategies:

1. OAuth 2.0

🔐 Overview: A protocol for authorization, allowing third-party access to resources without sharing credentials.

  • Use Cases: Social media logins, API access delegation
  • Advantages: Scalable, supports refresh tokens, granular permissions

2. JWT (JSON Web Token)

🔑 Overview: A compact token format that includes claims about the user and session.

  • Use Cases: Stateless authentication, Single Sign-On (SSO)
  • Advantages: Self-contained, no server-side storage required

3. API Gateway Integration

🔒 Overview: Centralized authentication layer that validates requests before routing.

  • Use Cases: Microservices architectures, rate limiting
  • Advantages: Simplifies security management, logs and monitors traffic
