FileVault

Encryption

Enable FileVault

  • Not configured (default)

  • Yes - Enable Full Disk Encryption using XTS-AES 128 with FileVault on devices that run macOS 10.13 and later. FileVault is enabled when the user signs off of the device.

    When set to Yes, you can configure additional settings for FileVault.

    • Recovery key type Personal key recovery keys are created for devices. Configure the following settings for the personal key:

      • Personal recovery key rotation
        Specify how frequently the personal recovery key for a device will rotate. You can select the default of Not configured, or a value of 1 to 12 months.
      • Escrow location description of personal recovery key
        Specify a short message to the user that explains how they can retrieve their personal recovery key. The user sees this message on their sign in screen when prompted to enter their personal recovery key if a password is forgotten.

    • Number of times allowed to bypass
      Set the number of times a user can ignore prompts to enable FileVault before FileVault is required for the user to sign in.

      • Not configured (default) - Encryption on the device is required before the next sign-in is allowed.
      • 1 to 10 - Allow a user to ignore the prompt from 1 to 10 times before requiring encryption on the device.
      • No limit, always prompt - The user is prompted to enable FileVault, but encryption is never required.

    • Allow deferral until sign out

      • Not configured (default)
      • Yes - Defer the prompt to enable FileVault until the user signs out.

    • Disable prompt at sign out
      Prevent the prompt to the user that requests they enable FileVault when they sign out. When set to Disable, the prompt at sign-out is disabled and instead, the user is prompted when they sign in.

      • Not configured (default)
      • Yes - Disable the prompt to enable FileVault that appears at sign-out.

    • Hide recovery key
      Hide the personal recovery key from the user of the macOS device during encryption. After the disk is encrypted, a user can use any device to view their personal recovery key through the Intune Company Portal website, or company portal app on a supported platform.

      • Not configured (default)
      • Yes - Hide the personal recovery key during device encryption.

BitLocker

Note

This article details the settings you can find in BitLocker profiles created before June 19, 2023, for the Windows 10 and later platform for endpoint security Disk encryption policy. On June 19, 2023, the Windows 10 and later profile was updated to use a new settings format as found in the Settings Catalog. With this change you can no longer create new versions of the old profile and they are no longer being developed. Although you can no longer create new instances of the older profile, you can continue to edit and use instances of it that you previously created.

For profiles that use the new settings format, Intune no longer maintains a list of each setting by name. Instead, the name of each setting, its configuration options, and its explanatory text you see in the Microsoft Intune admin center are taken directly from the settings authoritative content. That content can provide more information about the use of the setting in its proper context. When viewing a settings information text, you can use its Learn more link to open that content.

The following settings details for Windows profiles apply to those deprecated profiles.

BitLocker – Base Settings

  • Enable full disk encryption for OS and fixed data drives
    CSP: BitLocker - RequireDeviceEncryption

    If the drive was encrypted before this policy applied, no extra action is taken. If the encryption method and options match that of this policy, configuration should return success. If an in-place BitLocker configuration option doesn't match this policy, configuration will likely return an error.

    To apply this policy to a disk already encrypted, decrypt the drive and reapply the MDM policy. Windows default is to not require BitLocker drive encryption. However, on Microsoft Entra join and Microsoft Account (MSA) registration/login automatic encryption can apply enabling BitLocker at XTS-AES 128-bit encryption.

    • Not configured (default) - No BitLocker enforcement takes place.
    • Yes - Enforce use of BitLocker.

  • Require storage cards to be encrypted (mobile only)
    CSP: BitLocker - RequireStorageCardEncryption

    This setting only applies to Windows Mobile and Mobile Enterprise SKU devices.

    • Not configured (default) - The setting returns to the OS default, which is to not require storage card encryption.
    • Yes - Encryption on storage cards is required for mobile devices.

    Note

    Support for Windows 10 Mobile and Windows Phone 8.1 ended in August of 2020.

  • Hide prompt about third-party encryption
    CSP: BitLocker - AllowWarningForOtherDiskEncryption

    If BitLocker is enabled on a system that's already encrypted by a third-party encryption product, it might render the device unusable. Data loss can occur and you might need to reinstall Windows. It's highly suggested to never enable BitLocker on a device that has third-party encryption installed or enabled.

    By default, the BitLocker setup wizard prompts users to confirm that no third-party encryption is in place.

    • Not configured (default) – The BitLocker setup wizard displays a warning and prompts users to confirm no third-party encryption is present.
    • Yes - Hide the BitLocker setup wizards prompt from users.

    If BitLocker silent enable features are required, the third-party encryption warning must be hidden as any required prompt breaks silent enablement workflows.

    When set to Yes, you can then configure the following setting:

    • Allow standard users to enable encryption during Autopilot
      CSP: BitLocker - AllowStandardUserEncryption

      • Not configured (default) – The setting is left as client default, which is to require local admin access to enable BitLocker.
      • Yes - During Microsoft Entra join silent enable scenarios, users don't need to be local administrators to enable BitLocker.

      For non-silent enablement and Autopilot scenarios, the user must be a local admin to complete the BitLocker setup wizard.

  • Configure client-driven recovery password rotation
    CSP: BitLocker - ConfigureRecoveryPasswordRotation

    Add Work Account (AWA, formally Workplace Joined) devices aren't supported for key rotation.

    • Not configured (default) – The client won’t rotate BitLocker recovery keys.
    • Disabled
    • Microsoft Entra joined devices
    • Microsoft Entra hybrid joined devices
