Constructive feedback to improve security:

You can break into the system by holding CTRL+T (terminate). To disable this, you can add the following code at the beginning of the startup file:

oldOsPullEvent = os.pullEvent
os.pullEvent = os.pullEventRaw

The idea is that when you hold CTRL+T for a longer time, the event "terminate" will fire, and os.pullEvent will create an error to end the program currently running. os.pullEventRaw does not do this, that's why you are replacing the global reference to os.pullEvent with it.

Another tip: to stop people from breaking into the computer by crashing the OS, you could also enclose the whole startup program like this:

startup file:

local function main()

<startup file normally>

end

local success, message = pcall(main)

if not success then
  --you can print the crash error message here if you want, to let users send feedback

  os.reboot()
end

This will make sure that if the OS breaks, it reboots instead of letting users have full access to the CraftOS shell.

Also, security wise it is not a good idea to have the password hardcoded into the code. What you could do, is to save the password to a file during installation. It is pretty easy to do so, the function you can read/write files with is fs.open or use one of the config libraries from APIs and utilities on this forum
