> [!NOTE]
> The Windows Hello for Business PIN is not a symmetric key (a password). A copy of the current PIN is not stored locally or on a server like in the case of passwords. Making the PIN as complex and changed frequently as a password increases the likelihood of forgotten PINs. Additionally, enabling PIN history is the only scenario that requires Windows 10 to store older PIN combinations (protected to the current PIN). Windows Hello for Business combined with a TPM provides anti-hammering functionality that prevents brute force attacks of the user's PIN. If you are concerned with user-to-user shoulder surfacing, rather that forcing complex PIN that change frequently, consider using the [Multifactor Unlock](feature-multifactor-unlock.md) feature.
