Yes, it isn’t as hard as you think. Remember the best start on anything here is to check the code on the page, then ctrl and f sets up the find function on the page, you are looking for a password as you are on all the levels. When you find the variable they are using to store the password in, (could be password, past or anything really) when you find that and understand what is being used to implement it, look again at the source and you will find what you are looking for.
