- question: What's the difference between non-destructive and destructive PIN reset?
answer: |
Windows Hello for Business has two types of PIN reset: non-destructive and destructive. Organizations running Windows 10 Enterprise and Azure Active Directory can take advantage of the Microsoft PIN Reset service. Once on-boarded to a tenant and deployed to computers, users who have forgotten their PINs can authenticate to Azure, provide a second factor of authentication, and reset their PIN without reprovisioning a new Windows Hello for Business enrollment. This flow is a non-destructive PIN reset because the user doesn't delete the current credential and obtain a new one. For more information, see [PIN Reset](hello-feature-pin-reset.md).

Organizations that have the on-premises deployment of Windows Hello for Business, or those not using Windows 10 Enterprise can use destructive PIN reset. With destructive PIN reset, users that have forgotten their PIN can authenticate by using their password and then performing a second factor of authentication to reprovision their Windows Hello for Business credential. Reprovisioning deletes the old credential and requests a new credential and certificate. On-premises deployments need network connectivity to their domain controllers, Active Directory Federation Services, and their issuing certificate authority to perform a destructive PIN reset. For hybrid deployments, destructive PIN reset is only supported with the certificate trust model and the latest updates to Active Directory Federation Services.

Windows Hello for Business provides the capability for users to reset forgotten PINs using the "I forgot my PIN link" from the Sign-in options page in Settings or from above the lock screen. User's are required to authenticate and complete multifactor authentication to reset their PIN.
There are two forms of PIN reset called destructive and non-destructive. Destructive PIN reset is the default and does not require configuration. During a destructive PIN reset, the user's existing PIN and underlying credentials, including any keys or certificates added to their Windows Hello container, will be deleted from the client and a new logon key and PIN are provisioned. For non-destructive PIN reset, you must deploy the Microsoft PIN reset service and client policy to enable the PIN recovery feature. During a non-destructive PIN reset, the user's Windows Hello for Business container and keys are preserved, but the user's PIN that they use to authorize key usage is changed.

## Using PIN Reset
**Requirements**
- Reset from settings - Windows 10, version 1703
- Reset above Lock - Windows 10, version 1709
- Reset from settings - Windows 10, version 1703 or later, Windows 11
- Reset above Lock - Windows 10, version 1709 or later, Windows 11
Destructive and non-destructive PIN reset use the same entry points for initiating a PIN reset. If a user has forgotten their PIN, but has an alternate logon method, they can navigate to Sign-in options in Settings and initiate a PIN reset from the PIN options. If they do not have an alternate way to sign into their device, PIN reset can also be initiated from above the lock screen in the PIN credential provider.

When non-destructive PIN reset is enabled on a client, a 256-bit AES key is generated locally and added to a user's Windows Hello for Business container and keys as the PIN reset protector. This PIN reset protector is encrypted using a public key retrieved from the Microsoft PIN reset service and then stored on the client for later use during PIN reset. After a user initiates a PIN reset, completes authentication to Azure, and completes multifactor authentication, the encrypted PIN reset protector is sent to the Microsoft PIN reset service, decrypted, and returned to the client. The decrypted PIN reset protector is used to change the PIN used to authorize Windows Hello for Business keys and it is then cleared from memory.
