IAM Identity Center: Customer Managed App Account Access
🔐 IAM Identity Center now lets customer managed applications programmatically discover user-assigned AWS accounts and roles and retrieve temporary credentials for account access. If your application authenticates users via an external identity provider (IdP), you can configure that IdP as a trusted token issuer and enable AWS account access so users who already signed in through the IdP can obtain credentials without re-authenticating. Administrators must explicitly enable this for each customer managed application, and only management account or delegated administrators can grant the capability, ensuring centralized governance. The feature is available across all commercial, GovCloud (US), and China Regions.
