In this video, we explore API key authentication and introduce the concept of pre-authentication—a powerful security pattern used to offload authentication to upstream services like API gateways or identity providers. We’ll discuss:
✅ What is Pre-Authentication?
✅ When and why you should use this pattern.
✅ How API key authentication works in real-world applications.
✅ Best practices for securing your APIs with API keys.
1) Generating and Storing Encrypted API Keys
2) Securing Endpoints with API Keys
