Yeah, I guess master key usage is just a little too broad. Opening doors doesn't seem like a huge issue, but I would at least require a supplementary password entry for crucial functionality like disabling elevators.

- nathan_long 14y agoYeah, the question is really which potential harm is larger: unauthorized access, or the possible failure of authorized access? Then you need to ensure the system is more likely to fail in the less dangerous direction. Sounds like physical keys do that.
- precisioncoder 14y agoA second layer of protection for critical features that could cost lives is always a good idea. Have to balance authorized people using them with preventing unauthorized people from causing chaos, maybe a standardized pass code that changed once a month and all rescue workers received. If for instance 3d printers become household items and the key pattern is widely distributed online it could end up being a big problem.
