Ok, here’s a weird one to explain. The only way I could get a valid passcode format was with a 2×11 grid

Read down from the upper right F

Now don’t ask me how or why but the first hunch I had was that the keyword was skepsis…

In a case like this Morse or Vigenere would be my first try but nothing good came up. I then tried letters to numbers (a=0)

10 21 17 9 9 5 25 21 19 10 5 11 6 11 0 10 11 15 1 1 5 5 2 5 6 5 7 1 12 9 8

This actually gives a pretty good range. Let’s rearrange it for Ascii

102 117 99 52 52 119 105 116 110 101 115 115 52 56 57 112 98

Convert decimal to Ascii

In Japanese, witness translates to shonin

Start by making pairs to see what you have to work with

d4 64 a5 04 82 33 85 05 13 03 25 33 25 63 63 23 74 64

Reversing it will put everything more closely to a good Ascii range

46 47 32 36 36 52 33 52 30 31 50 58 33 28 40 5a 46 4d

Convert Hex to Ascii

Let’s reverse everything again

MFZ@(3XP10R3R662GF

Now convert those symbols to numbers and the keyword is leetspeak
