AD Connector enables you to use your existing on-premises Microsoft Active Directory (AD) identities to access the AWS Management Console and compatible AWS applications, such as Amazon WorkSpaces, Amazon Connect, and Amazon Chime . With AD Connector, you can enable multi-factor authentication (MFA) for AWS applications users and use your existing RADIUS-based infrastructure for an additional layer of security. You also can join Amazon EC2 Windows instances to your on-premises AD domain and manage the instances using group policy objects.
