This can be applied to almost anything from running strings of code if you get the password right to making logins for games. If anyone finds a more efficient way to do the please share it with me. This is the shortest version that I could make and I'm trying to make a game that uses a login and this you can only use once. So if you improve it please share it.
That's cool, I'm working on a Savable Password System for my Operating System made with python.
