Un Usual Question (for kuya admin, kuya emond and kuya jake) and for the others that know this

I was watching some programs and this one program really catches my attention. The Login Failed 3 times then Lock the system and never open again. In some cases if you fail to login 3 times you can just run the program again. But the program that I saw was made me amazed. If you fail to login 3 times, the system will lock and if you try to run it, it will never run. My point of this is I want to gather info about how this system locks and never be open is done and what is the codes needed. And also how to unlock or run it again after failing 3 times.
