title: Disable TouchID for Unlocking the Device
discussion: |
  TouchID enables the ability to unlock a Mac system with a user's fingerprint.

  TouchID _MUST_ be disabled for "Unlocking your Mac" on all macOS devices that are capable of using Touch ID.

  The system _MUST_ remain locked until the user establishes access using an authorized identification and authentication method.

  NOTE: TouchID is not an approved biometric authenticator for US Federal Government usage as it has not been verified to meet the strength requirements outlined in NIST SP 800-63.
