You can change your external identity provider's metadata which you previously supplied to the IAM Identity Center. These changes affect your users' ability to sign in and access AWS resources through IAM Identity Center. The following procedure describes how to update your external IdP's metadata that is stored in IAM Identity Center. To complete this procedure, you'll need an Organization instance of IAM Identity Center. For more information, see [Organization and account instances of IAM Identity Center](identity-center-instances.md).
