Enable seamless second factor authentication
Seamless second factor authentication is an enhancement in AD FS that provides an added level
of access protection to corporate resources and applications from external devices that are trying
to access them. When a personal device is Workplace Joined, it becomes a `known’ device and
administrators can use this information to drive conditional access and gate access to resources.
To enable seamless second factor authentication, persistent single sign-on (SSO) and conditional
access for Workplace Joined devices
In the AD FS Management console, navigate to Authentication Policies. Select Edit Global Primary
Authentication. Select the check box next to Enable Device Authentication, and then click OK.
