title: Enable Firmware Password
discussion: |
A firmware password _MUST_ be enabled and set.
Single user mode, recovery mode, the Startup Manager, and several other tools are available on macOS by holding the "Option" key down during startup. Setting a firmware password restricts access to these tools.
To set a firmware passcode use the following command:
[source,bash]
----
/usr/sbin/firmwarepasswd -setpasswd
----
NOTE: If firmware password or passcode is forgotten, the only way to reset the forgotten password is through the use of a machine specific binary generated and provided by Apple. Schedule a support call, and provide proof of purchase before the firmware binary will be generated.
NOTE: Firmware passwords are not supported on Apple Silicon devices. This rule is only applicable to Intel devices.
check: |
/usr/sbin/firmwarepasswd -check | /usr/bin/grep -c "Password Enabled: Yes"
result:
integer: 1
fix: |
NOTE: See discussion on how to enable firmware password.
