AWS Multi-Factor Authentication (MFA) is a simple best practice that adds an extra layer of protection on top of your user name and password. With MFA enabled, when a user signs into the AWS GovCloud (US) region, they will be prompted for their user name and password (the first factor—what they know), as well as for an authentication code from their AWS MFA device (the second factor—what they have). Taken together, these multiple factors provide increased security for your GovCloud account settings and resources.

You can enable MFA for your GovCloud account and for individual IAM users you have created under your account. MFA can be also be used to control access to AWS GovCloud service APIs. After you've obtained a supported hardware or virtual MFA device, AWS does not charge any additional fees for using MFA.

For more information on Virtual MFA Devices, see the AWS MFA web page.
