Not really a good Decimal to Ascii string but looking at the distribution the lowest number is 86 and highest 108.
108-86=22 this could hint to a numbers to letters string. Just need to find the right number to subtract from.
Assuming that the highest number of the code would be XX it would give us (10*10)+10=110
So from 110 subtract all values above (110-106, 110-102,…) to get: 4 8 24 10 1 18 4 2 14 13 18 15 8 17 4 14 5 8 9 5 14 13

Observations
Converting Hexadecimal to Ascii doesn’t give anything good but it really looks like Hex.

Making pairs will somewhat reveal the encode c9 9c 90 9d cb 8f 9e 96 91 8b 94 cb 8c ca 9d
Looking at where the numbers should fall in the regular passcode format you can notice that they all start with C
In Hexadecimal values 30 to 39 convert 0 to 9 in Ascii. How can we make C=3 ?

Observations
All letters, so many possibilities, need to try each and everyone…
Atbash? Rot? Morse? Playfair? BiFid?
Well none of them gave something except for ROT-3 which gave evifqwfhmhyyoanowwtyizucx
That five was actually just pure coincidence
When all else fails I usually try to brute Vigenere the string.
The way I do it is to put in TWO, THREE, FOUR and so on as the passphrase using the Vigenere Autokey cipher. This will sometime reveal a keyword to use to decode the string. In this case still nothing.
When even that fails remember to always try Vigenere Autokey with abcdefghijkl…. or simply “a” and bingo!
