Amazon Cognito now supports access token customization for machine-to-machine (M2M) authorization flows

Amazon Cognito has introduced access token customization for machine-to-machine (M2M) authorization flows, providing enhanced control and flexibility for automated system interactions.

• Enables fine-grained authorization for automated processes like data synchronization, microservices communication, and event-driven workflows
• Allows customers to add custom claims and scopes directly to access tokens
• Reduces complexity of authorization logic in application code
• Provides example of differentiating access levels between reporting and data processing systems
• Available in Cognito Essentials and Plus tiers across most AWS Regions

This feature streamlines authentication by embedding custom authorization attributes directly into access tokens during token issuance, simplifying how automated systems interact and manage access.
