Who knows what it could be? Hint: It's my favourite train ID and a type of encryption without the '.' is the amount of numbers. If you hear a sound and the prompt does NOT come back up, you've cracked it or figured it out. The quickly-increasing number is a random check to see if you've got it or not. Seeing it is incredibly unlikely, unless you've cracked it. (e.g. String1 = 12345, String2 = 12335, it checks a random letter of both and if it matches, it tries the next one and etc).
Only I have beaten it! (Of course, I know the passcode!)
