AWS IAM Identity Center helps administrators centrally manage access to multiple AWS accounts that are members of an AWS Organization. End users can authenticate and then access all their AWS accounts from a single interface. Using IAM Identity Center as a SAML identity provider for your AWS accounts also has security benefits: user credentials provided via federation are temporary. IAM Identity Center does not automatically detect AWS GovCloud (US) accounts associated with standard AWS accounts in your AWS Organization. IAM Identity Center is also not currently available in AWS GovCloud (US). As a result, IAM Identity Center cannot be used to automatically provision access for your users into an AWS GovCloud (US) account. However, this functionality can be extended to enable federation into AWS GovCloud (US) with a “custom SAML 2.0 application” in IAM Identity Center.
