If access depends upon supplying the correct code in response to a prompt, 
why can't such codes be relatively short? If the access routine only 
permits repeat entry attempts at, say, 30 second intervals, a modest code 
that is easily breached with unlimited retries becomes effectively 
unbreakable. Processor speed would become irrelevant. Am I missing 
something here?
