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 Remote Authentication Dial-In User Service (RADIUS)–based infrastructure for an additional layer of security. You also can join Amazon EC2 instances to your on-premises AD domain and manage the instances using Group Policy objects.
