A method, computer program product and system for storing or updating authentications, e.g., passwords, in a boot code image, i.e., binary executable boot code, stored within a Read Only Memory (ROM), e.g., flash ROM, of a terminal from a remote central site. An authentication may be stored in the boot code image in a terminal from a central site by creating a file comprising a boot code image storing the authentication at the central site and then storing the created file in ROM in the terminal. The file may be downloaded from a server at the central site to the terminal. An authentication in the boot code image in a terminal may be updated remotely from a central site by updating the file associated with the boot code image, i.e., updating the authentication, at the central site and then downloading the updated file to the terminal.
