Additionally, lights out data centers can take advantage of the enhanced security of a second factor while avoiding the need for user intervention during reboots by optionally using a combination of BitLocker (TPM+PIN) and BitLocker Network Unlock. BitLocker Network Unlock brings together the best of hardware protection, location dependence, and automatic unlock, while in the trusted location. For the configuration steps, see [BitLocker: How to enable Network Unlock](bitlocker-how-to-enable-network-unlock.md).
