Authentication/AllowFidoDeviceSignon

Edition Windows 10 Windows 11
Home No No
Pro Yes Yes
Business Yes Yes
Enterprise Yes Yes
Education Yes Yes

Scope:

  • Device

Supported in the next release. Specifies whether Fast Identity Online (FIDO) device can be used to sign on. This policy enables the Windows logon credential provider for FIDO 2.0

Value type is integer.

Here's an example scenario: At Contoso, there are many shared devices and kiosks that employees use throughout the day, for example, employees use as many as 20 different devices. To minimize the loss in productivity when employees have to sign in with username and password every time they pick up a device, the IT admin deploys SharePC CSP and Authentication/AllowFidoDeviceSignon policy to shared devices. The IT admin provisions and distributes FIDO 2.0 devices to employees, which allows them to authenticate to various shared devices and PCs.

The following list shows the supported values:

  • 0 - Don't allow. The FIDO device credential provider disabled.
  • 1 - Allow. The FIDO device credential provider is enabled and allows usage of FIDO devices to sign in to Windows.

Authentication/AllowSecondaryAuthenticationDevice

Edition Windows 10 Windows 11
Home No No
Pro Yes Yes
Business Yes Yes
Enterprise Yes Yes
Education Yes Yes

Scope:

  • Device

Allows secondary authentication devices to work with Windows.

The default for this policy must be on for consumer devices (defined as local or Microsoft account connected device) and off for enterprise devices (such as cloud domain-joined, cloud domain-joined in an on-premises only environment, cloud domain-joined in a hybrid environment, and BYOD).

In the next major release of Windows 10, the default for this policy for consumer devices will be changed to off. This change will only affect users that have not already set up a secondary authentication device.

ADMX Info:

  • GP Friendly name: Allow companion device for secondary authentication
  • GP name: MSSecondaryAuthFactor_AllowSecondaryAuthenticationDevice
  • GP path: Windows Components/Microsoft Secondary Authentication Factor
  • GP ADMX file name: DeviceCredential.admx

The following list shows the supported values:

  • 0 – Not allowed.
  • 1 – Allowed.

Authentication/ConfigureWebSignInAllowedUrls

Edition Windows 10 Windows 11
Home No No
Pro Yes Yes

Education Yes Yes

Scope:

  • Device

Specifies the list of domains that are allowed to be navigated to in AAD PIN reset and Web Sign-in Windows device scenarios where authentication is handled by AD FS or a third-party federated identity provider. Note this policy is required in federated environments as a mitigation to the vulnerability described in CVE-2021-27092.

Example: If your organization's PIN reset or Web Sign-in authentication flow is expected to navigate to two domains, accounts.contoso.com and signin.contoso.com, the policy value should be "accounts.contoso.com;signin.contoso.com".

Home No No
Pro Yes Yes
Business Yes Yes
Enterprise Yes Yes
Education Yes Yes

Scope:
