firmwarepasswd
FIRMWAREPASSWD(8) BSD System Manager's Manual FIRMWAREPASSWD(8)
NAME
firmwarepasswd -- tool for setting and removing firmware passwords on a system
SYNOPSIS
firmwarepasswd [-setpasswd] [-setmode mode] [-mode] [-check] [-delete] [-verify] [-unlockseed] [-h]
DESCRIPTION
The firmwarepasswd command is used to add or remove firmware passwords from a system as well as check status and other options. The
firmwarepasswd command requires root privileges to run.
A list of flags and their descriptions:
-setpasswd
Prompts to add a new firmware password or change and existing password if one exists.
-setmode mode
Set the mode to "command" or "full". "Command" will prompt for the firmware password if the user attempts to boot from a different
volume. "Full" will prompt on every startup (not recommended).
-mode Displays the current mode if one is set.
-check Displays whether or not a firmware password is set.
-delete
Prompts for password and clears both password and the mode if correct.
-verify
Prompts for password and displays success if correct.
-unlockseed
Generates a firmware password recovery key. Note: Machine must be stable for this command to generate a valid seed. No pending
changes that need a restart. NOTE: Seed is only valid until the next time a firmware password command runs.
-h Displays a list of all the commands available in the firmwarepasswd tool, with explanatory information.
