Application Load Balancer now supports client credential flow with JWT verification

Amazon Web Services (AWS) announces JWT Verification for Application Load Balancer (ALB), enabling secure machine-to-machine (M2M) and service-to-service (S2S) communications. This feature allows ALB to verify JSON Web Tokens (JWTs) included in request headers, validating token signatures, expiration times, and claims without requiring modifications to application code.

By offloading OAuth 2.0 token validation to ALB, customers can significantly reduce architectural complexity and streamline their security implementation. This capability is particularly valuable for microservices architectures, API security, and enterprise service integration scenarios where secure service-to-service communication is critical. The feature supports tokens issued through various OAuth 2.0 flows, including Client Credentials Flow, enabling centralized token validation with minimal operational overhead.

The JWT Verification feature is now available in all AWS Regions where Application Load Balancer is supported.
