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.

NAME

       dxchpwd - Create or change password program

SYNOPSIS

       dxchpwd

       dxchpwd -r  | -l

       dxchpwd [-r  | -l] -q

       dxchpwd [-r  | -l] -u  username

OPTIONS

       If dxchpwd is invoked without any options, it is assumed that the current user's password is to be changed.  The following options are also
       accepted: Tells dxchpwd that the password change is to be done for a Local user. This can be combined with the -u and  -q  options.   Tells
       dxchpwd	that the password change is to be done for a NIS user. This can only be done from a NIS master and can be combined with the -u and
       -q options.  Tells dxchpwd to query the user for the user name of the account whose password is to be changed.	Tells  dxchpwd	to  change
       this user's password.

DESCRIPTION

       The  dxchpwd  command lets you change your password.  When you invoke the dxchpwd command, the program prompts you for the old password and
       then for the new password.  Next, the program asks you for the new password again, to verify that you have typed it correctly.	Note  that
       the passwords are not displayed on the screen.

       Your new password must meet the length requirements specified by the authorization database for the user whose password is being changed.

       If  your system is running with enhanced security, you may have to choose a password from a list of randomly generated passwords or you may
       be prohibited from changing your password until its minimum lifetime has expired, as specified in the authorization database.

EXAMPLES

       The following example requests that the password be changed for user smith: dxchpwd -u smith
