 Because the dial points at `0` a total of three times during this process, the password in this example is _`3`_.
 
 Analyze the rotations in your attached document. _What's the actual password to open the door?_

+### Part Two
+
+You're sure that's the right password, but the door won't open. You knock, but nobody answers. You build a snowman while you think.
+
+As you're rolling the snowballs for your snowman, you find another security document that must have fallen into the snow:
+
+"Due to newer security protocols, please use _password method <span title="You should have seen the chaos when the Elves overflowed their 32-bit password method counter.">0x434C49434B</span>_ until further notice."
+
+You remember from the training seminar that "method 0x434C49434B" means you're actually supposed to count the number of times _any click_ causes the dial to point at `0`, regardless of whether it happens during a rotation or at the end of one.
+
+Following the same rotations as in the above example, the dial points at zero a few extra times during its rotations:
+
+*   The dial starts by pointing at `50`.
+*   The dial is rotated `L68` to point at `82`; during this rotation, it points at `0` _once_.
+*   The dial is rotated `L30` to point at `52`.
+*   The dial is rotated `R48` to point at _`0`_.
+*   The dial is rotated `L5` to point at `95`.
+*   The dial is rotated `R60` to point at `55`; during this rotation, it points at `0` _once_.
+*   The dial is rotated `L55` to point at _`0`_.
+*   The dial is rotated `L1` to point at `99`.
+*   The dial is rotated `L99` to point at _`0`_.
+*   The dial is rotated `R14` to point at `14`.
+*   The dial is rotated `L82` to point at `32`; during this rotation, it points at `0` _once_.
+
+In this example, the dial points at `0` three times at the end of a rotation, plus three more times during a rotation. So, in this example, the new password would be _`6`_.
+
+Be careful: if the dial were pointing at `50`, a single rotation like `R1000` would cause the dial to point at `0` ten times before returning back to `50`!
+
+Using password method 0x434C49434B, _what is the password to open the door?_
