For increased security, we recommend that you configure multi-factor authentication (MFA) to help protect your AWS resources. You can enable MFA for the AWS account root user and IAM users. When you enable MFA for the root user, it affects only the root user credentials. IAM users in the account are distinct identities with their own credentials, and each identity has its own MFA configuration. You can register up to eight MFA devices of any combination of the currently supported MFA types with your AWS account root user and IAM users. For more information about supported MFA types see What is MFA?. With multiple MFA devices, only one MFA device is needed to sign into the AWS Management Console or create a session through the AWS CLI as that user.
