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
