Having been involved in new products ranging from consumer electronics to security devices, the problem with this is that people will get too creative with their passwords, forget them, and then get mad when a factory default loses all settings. In my experience, it's a losing battle no matter how you approach it. Make people specify a password, but then often times one person stages it and another installs it, so do you make an easy password for staging it? Do you add the overhead of making a device that enforces strong passwords? And so on... The closest thing to a best solution I've seen is a 2-factor system, a passcode along with some kind of hardware dongle to default or get admin access.
