I went through the tutorial. Seems very cool. Disappointed that "password" worked though - I thought it would show me how to read the value my input was compared to instead of just matching the string (and lucky guessing).
Funnily enough, I had to refresh once or twice during the tutorial, and I started realizing that it was checking it against a known number (9).
Your input wasn't really compared against anything but its length. It took me a good minute, but I figured that out before it told me the password. (because of the tutorial)
