--- author: paolomatarazzo ms.author: paoloma ms.date: 10/30/2023 ms.topic: include --- ### Require device encryption This policy setting determines whether BitLocker is required: - If enabled, encryption is triggered on all drives silently or non-silently based on [Allow warning for other disk encryption](../configure.md?tabs=os#allow-warning-for-other-disk-encryption) policy - If disabled, BitLocker isn't turned off for the system drive, but it stops prompting the user to turn BitLocker on. > [!NOTE] > Typically, BitLocker follows the [Choose drive encryption method and cipher strength](../configure.md?tabs=os#choose-drive-encryption-method-and-cipher-strength) policy configuration. However, this policy setting will be ignored for self-encrypting fixed drives and self-encrypting OS drives. Encryptable fixed data volumes are treated similarly to OS volumes, but they must meet other criteria to be encryptable: - It must not be a dynamic volume - It must not be a recovery partition - It must not be a hidden volume - It must not be a system partition - It must not be backed by virtual storage - It must not have a reference in the BCD store > [!NOTE] > Only full disk encryption is supported when using this policy for silent encryption. For non-silent encryption, encryption type will depend on the [*Enforce drive encryption type on operating system drives*](../configure.md?tabs=fixed#enforce-drive-encryption-type-on-operating-system-drives) and [*Enforce drive encryption type on fixed data drives*](../configure.md?tabs=fixed#enforce-drive-encryption-type-on-fixed-data-drives) policies configured on the device. | | Path | |--|--| | **CSP** | `./Device/Vendor/MSFT/BitLocker/`[RequireDeviceEncryption](/windows/client-management/mdm/bitlocker-csp#requiredeviceencryption) | | **GPO** | Not available |
