As micro-frontend architectures gain traction for their modularity and scalability, they introduce a new layer of complexity in managing authentication and authorization across distributed frontend modules. In ecosystems where multiple teams independently deploy micro-frontends, often with different tech stacks, the challenge is ensuring consistent, secure identity management without tightly coupling authentication logic. Developers frequently struggle with session propagation, token management, and enforcing fine-grained access controls across isolated apps. This leads to brittle security implementations, duplicated logic, and increased risk of misconfigurations in federated environments.

In this session, I’ll demonstrate how to securely integrate AWS Cognito and IAM into micro-frontend architectures using proven patterns like centralized identity providers, token delegation, and fine-grained role-based access controls. I’ll cover how to architect micro-frontends that authenticate through a unified Cognito user pool, securely share and validate JWTs across federated modules, and use IAM to enforce backend access policies per user role and frontend domain. The talk includes real-world code examples, CI/CD integration patterns, and security best practices to avoid common pitfalls like token leakage, improper scoping, or over-permissive IAM roles.

Attendees will walk away with actionable knowledge such as;

- Learn how to design secure and scalable micro-frontend architectures using AWS Cognito and IAM as the foundation for identity management.

- Understand how to prevent critical security issues, including misconfigured redirect URIs, poor session management, and excessive privilege exposure.

- Gain practical insights for both platform engineers enforcing consistent security standards and frontend developers integrating seamless auth flows.

- Develop the ability to strike the right balance between flexibility and security in distributed, federated UI architectures.

- Acquire tested patterns and best practices for building resilient micro-frontend platforms without compromising identity and access governance.
