Hi Steve:
A possible analogy might be providing a 3-to-2-wire adaptor for your product. Clearly, doing so results in a misuse of the product (operating a Class 1 product without a ground). Safety standards require the product be safe in the event of misuse. Giving the password to a customer results, in my opinion, in misuse of the product, which, according to many safety standards, is a condition which must be safe. Providing a password to one customer means that all customers may get the password from the first customer. Your manufacturer loses control of the password and might as well not use a password.

I believe, that other than it being a terrible idea, that it would probably invalidate any approvals the end product had. The customer is asking for a document that supports my opinion. I dud suggest that we send a service person to do the change, and not give up the pw. Thoughts?
