Windows Hello policy to sync PIN code between devices
It would be really cool if we could have Windows Hello manage and standardize a user's PIN code policy. For example, we specify a PIN code expiration policy for every 30 days. Every 30 days a user sets a new Windows Hello pin code which is synced to all devices registered to that user. Additionally, this Win Hello PIN code could also be applied to pin code protected managed apps.
Take it a step further, a PC Windows Hello policy that specifies a user may only use Windows Hello PIN to login to their PC if a registered mobile device is present.
This way a user would only have one PIN code to remember between registered devices and if they forgot their PIN, they could login to their PCs using another method (username/password) then reset their Windows Hello PIN from their Win10 PC which then would sync to their devices. This could serve as not only a convenience factor but also a self service PIN code reset mechanism.
This defeats the purpose of a PIN, it's meant to be device specific.
