AWS account root user - AWS Identity and Access Management

AWS account root user

When you first create an Amazon Web Services (AWS) account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. This identity is called the AWS account root user and is accessed by signing in with the email address and password that you used to create the account.

Important

We strongly recommend that you don't use the root user for your everyday tasks and that you follow the root user best practices for your AWS account. Safeguard your root user credentials and use them to perform the tasks that only the root user can perform. For the complete list of tasks that require you to sign in as the root user, see Tasks that require root user credentials.

The following topics detail management tasks associated with the root user.
