IAM Identity Center users in the AWS Management Console
AWS IAM Identity Center users must change their password from an AWS access portal. For more information, see Resetting your AWS IAM Identity Center user password in the User Guide.
An IAM Identity Center user is a user whose AWS account is part of AWS Organizations who signs in through the AWS access portal with a unique URL. These users can be either created directly in the users in IAM Identity Center or in Active directory or another external identity provider.
