Linux in a Nutshell, 6th Edition

password

Synopsis

password [--md5] passwd [file]

Set a password for the menu interface. If used in the global section of the configuration file, outside the menu entries, GRUB prompts for a password before processing an a, e, or c entered by the user. Once the password passwd has been entered, if no file was specified, GRUB allows the user to proceed. Otherwise, GRUB loads the file as a new configuration file and restarts Stage 2. If password appears in an individual menu entry, GRUB prompts for the password before continuing. Specify --md5 to tell GRUB that the password was encrypted with the md5crypt command.
