The code was found in the image and you can notice that it has the same length of [2] and [3] so they are probably related. Note: The codes are already in the correct order and there is nothing that helps for reordering but finding some reference to a prefix/suffix/keyword.
[hint]
Try to join the three strings and reverse, you may notice something.
[/hint]
Spoiler
Make one string from the three codes and you will get snkqwoxxfjywephyytjudxclrearwtciroiotbpwqijjfcxafydsorpmegfs.
Notice that reading backwards each three letters you find an interesting string, so reverse it might be a starting point: sfgemprosdyfaxcfjjiqwpbtoiorictwraerlcxdujtyyhpewyjfxxowqkns.
Reading each three letters is equal to skip 3: serdafiportaldthwfokfmoyxjqbiiwecuypyxwngpsfcjwtocrrxjyejxqs
So as first passcode we got serdafiportaldthwfok. 7rda5portald3w4k
Code #2
Observations
The string can be divided into three:
serdafiportaldthwfok
fmoyxjqbiiwecuypyxwn
gpsfcjwtocrrxjyejxqs
[hint]
Two strings of the same length, the one already “passcoded” might be a key for something.

Spoiler
Apply Vigenére Cipher on fmoyxjqbiiwecuypyxwn with serdafiportaldthwfok as passphrase to get nixvxeimurderrficsid.
9xvx8murderr5c6d
Code #3
Observations
We now have:
serdafiportaldthwfok
nixvxeimurderrficsid
gpsfcjwtocrrxjyejxqs
Spoiler
Apply Vigenére Cipher on gpsfcjwtocrrxjyejxqs with nixvxeimurderrficsid as passphrase to get thvkffohulongstwhfip.
