You have to love Snew... always making it hard...
I'm tending to believe the interpretation that the "password (or person) is right in front of your face...
Since Heidi has been mentioned by C1, milkshaky and several other better known spoilers for this boot, I think he's saying that the boot is right in front of us, Heidi, due to all the spoilers...
There are lots of detailed guesses out there, but, usually, even when cryptic, Snews pics are very obvious if you don't "overthink" his cryptic stuff.
I'm just hoping that I haven't "overthought" his riddle.
