This policy setting controls whether or not a PIN is required for pairing to a wireless display device. The recommended state for this setting is: Enabled: First Time OR Enabled: Always. Rationale: If this setting is not configured or disabled then a PIN would not be required when pairing wireless display devices to the system, increasing the risk of unauthorized use. Impact: The pairing ceremony for connecting to new wireless display devices will always require a PIN.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled: First Time OR Enabled: Always: Computer Configuration\Policies\Administrative Templates\Windows Components\Connect\Require pin for pairing Note: This Group Policy path may not exist by default. It is provided by the Group Policy template WirelessDisplay.admx/adml that is included with the Microsoft Windows 10 Release 1607 & Server 2016 Administrative Templates (or newer). The new Choose one of the following actions sub-option was later added as of the Windows 10 Release 1809 Administrative Templates. Choosing Enabled in the older templates is the equivalent of choosing Enabled: First Time in the newer templates. Default Value: Disabled. (A PIN is not required for pairing to a wireless display device.)
