AWS IAM roles
AWS IAM roles are the key to moving between AWS accounts, integrating with your identity provider, and ridding your organization of risky, long-lived AWS credentials. Substrate helps you manage access by the names of your environments and services instead of by inscrutable 12-digit account numbers so that the access you grant is exactly what your business needs.
Substrate is the best tool for managing IAM roles for cross-account access, rendering this notoriously complicated aspect of AWS simpler to help you avoid leaks and compromises.
