Tasks that require root user credentials

We recommend that you use an IAM user with appropriate permissions to perform tasks and access AWS resources. However, you can perform the tasks listed below only when you sign in as the root user of an account.

Tasks

Change your account settings. This includes the account name, email address, root user password, and root user access keys. Other account settings, such as contact information, payment currency preference, and Regions, do not require root user credentials.

Restore IAM user permissions. If the only IAM administrator accidentally revokes their own permissions, you can sign in as the root user to edit policies and restore those permissions.

Activate IAM access to the Billing and Cost Management console.

View certain tax invoices. An IAM user with the aws-portal:ViewBilling permission can view and download VAT invoices from AWS Europe, but not AWS Inc or Amazon Internet Services Pvt. Ltd (AISPL).

Close your AWS account.

Change your AWS Support plan or Cancel your AWS Support plan. For more information, see IAM for AWS Support Register as a seller in the Reserved Instance Marketplace. Configure an Amazon S3 bucket to enable MFA (multi-factor authentication) Delete. Sign up for GovCloud.

Edit or delete an Amazon S3 bucket policy that includes an invalid VPC ID or VPC endpoint ID.
