Computer lock bugs

Hi everyone. I am working on a computer lock program (Not telling the name of it). But its got bugs that i can't fix.

Can you fix them?

I need the program to:

Loop round until a correct password has been inputted.

Automatically start the program after 20 minutes.

Cannot be terminated or rebooted.

Here is the code:

-- Computer Lock
--By FoxData
os.pullEvent = os.pullEventRaw
while true do
term.clear()
term.setCursorPos(10,5)

local password = "changethis"
print("This Machine has been locked")
term.setCursorPos(5,10)
print("Please Enter your password:")
term.setCursorPos(33,10)
local input = read("*")
if input == password then os.reboot()
else
error("Password is wrong")
end
  end  

Thing about what happens when any program throws an error (which is not caught).

Additionally think about how a CC computer starts up.


With this information, have a look at what your code is doing on it's last 5 lines

You cannot prevent Control+R or Control+S.

That code should work by replacing os.reboot (why???), with break.
