API Gateway serves as a centralized entry point for accessing AWS services over HTTP, offering features like authorizers to secure API endpoints and prevent unauthorized access. Authorizers act as a security measure by verifying incoming requests before allowing them to reach the backend service, with options like JWT and Lambda authorizers providing different levels of flexibility and complexity. JWT authorizers utilize OpenID Connect Discovery endpoints to validate tokens, while Lambda authorizers allow custom code to determine request validity, supporting both REST and HTTP API Gateway types. Clerk's use of JWTs is compatible with API Gateway authorizers, enhancing security through session tokens, and enabling fine-tuned access control by modifying session tokens to include additional claims. The article explains how to configure both JWT and Lambda authorizers with Clerk, emphasizing the importance of securely managing API access to avoid risks like data exfiltration or unexpected AWS bills.

Passkeys represent a significant advancement towards a passwordless future by enabling users to sign in using their devices or biometric data, offering both convenience and security through public-key cryptography. These cryptographically generated keys, stored on devices like smartphones or hardware tokens, consist of a public key sent to the service and a private key kept securely on the device, ensuring a secure login process without manually entering information. Passkeys surpass traditional username and password methods by providing built-in multifactor authentication, eliminating the risk of password reuse and phishing attacks, and enhancing credential strength against brute-force attempts. Their integration into services, such as those supported by Clerk, allows users to easily adopt this secure authentication method, marking a shift towards more streamlined and safer digital experiences.
