macOS provides multiple methods to protect the data on a Mac: a user account password, encryption via FileVault, and optional low-level security measure that prevents starting up from storage devices other than the selected startup disk. That's known as the firmware password or EFI (Extensible Firmware Interface) lock, which will also block the user's ability to use all startup key combinations, except the NVRAM or PRAM reset combinations. This command (Option + Command + P + R), however, will initiate the machine from macOS Recovery instead.
The Lost Mode feature of Find My Mac will remotely lock the Mac with a firmware password for one-time use. The user's Mac receives the lock instruction from iCloud, restarts, and asks for the system lock PIN code that they set up. After entering the passcode the Mac starts up from the designated startup disk and disables the passcode.

Turn Off Mac Firmware Password
Earlier versions of macOS required manual installation of the firmware but, starting in 2015, Apple began bundling EFI updates with the macOS updates in order to deliver security patches to all users. But as security firm Duo Labs discovered in late 2017, some Macs aren't getting the right firmware, which makes them vulnerable to hackers. They recommend checking the firmware version and updating if needed.
Firmware Passcode Location
On Intel-based Macs shipped before 2011, the firmware password was stored in the PRAM and read by the system EFI firmware before other PRAM variables. That lead to a serious security issue, allowing the firmware to be revealed in a native macOS app and weakening the enhanced security Apple had hoped to introduce with the addition of the firmware password.
In 2011, however, Apple added an important change to the system: the firmware password was moved to a separate programmable controller from Atmel. This component contains lockable flash memory to store the password and requires special programming with identifier numbers for both the Mac's motherboard and the Atmel chip to access and reset it.
Since the controller is an independent component, the only way to bypass it is to manually remove it from the motherboard, but this requires highly precise reflow soldering tools and techniques.
