Observations

Remember, apply the same method to the keyword !

Let’s split into the passcode format assuming symbols would become numbers

kuj#$ != ^%!ud

Convert symbols to their respective numbers on the keyboard except for the keyword part

kuj34 != 651ud

Atbash the prefix and suffix

pfq76 != 459fw

!= means “not equal”, the opposite would be equal

pfq76equal459fw

15 characters with the right amount of numbers for a valid passcode

Make a 3×5 grid

Reverse rows 2 & 4

gggghffbfbhagjhghdghhdgffbfefdihib

The range is now a to j. Convert letters to numbers using a = 0

6 6 6 6 7 5 5 1 5 1 7 0 6 9 7 6 7 3 6 7 7 3 6 5 5 1 5 4 5 3 8 7 8 1

Make pairs
