@siam yeah I am not talking about the wifi SSID and password. I am talking about more of how when you log into Linux and you have to provide a user and password. The idea is to keep unauthorized people from using the 3D printer.

I was wondering if password protection exist or can be added to the firmware. When I mean protection. Requiring the user to enter a password in order to start or stop a print and before making any changes to its configuration or connecting it to a network. The printer I am building at work requires some way of making sure no one can tamper with it.
