while true do
    os.pullEvent = os.pullEventRaw
        term.clear()
        term.setCursorPos(1, 1)
            write("Please Enter Password: ")
            input = read("*")
                if input == "Password" then
                    redstone.setOutput("right", true)
                        sleep(3)
                    redstone.setOutput("right", false)
                        sleep(1)
                    os.reboot()
                else
                    print("Incorrect! Try again later.")
                        sleep(1)
                    print("Shutting Down")
                        sleep(1)
                    os.reboot()
                end
