There should be a post-installation screen to setup the initial username and password when login is enabled
People probably don't always change the password so the defaults are out in the wild. People will be more conscious of the security of their installations when they are presented with the opportunity to set their own username and password from the start.

On some equipments, I saw an annoying popup each time you log with the default user/pass. It can be handy for integrators that want to keep the default l/p before delivering the app to the client and the client would want to change it to not be bothered each time he logs on.
