## Policy conflicts from multiple policy sources
Windows Hello for Business is designed to be managed by Group Policy or MDM but not a combination of both. If policies are set from both sources it can result in a mixed result of what is actually enforced for a user or device.
Policies for Windows Hello for Business are enforced using the following hierarchy: User Group Policy > Computer Group Policy > User MDM > Device MDM > Device Lock policy. All PIN complexity policies are grouped together and enforced from a single policy source.
Use a hardware security device and RequireSecurityDevice enforcement are also grouped together with PIN complexity policy. Conflict resolution for other Windows Hello for Business policies is enforced on a per policy basis.
>[!NOTE]
> Windows Hello for Business policy conflict resolution logic does not respect the ControlPolicyConflict/MDMWinsOverGP policy in the Policy CSP.
