There is no need to set it in an array. You can use the substring operator to get each individual character. It works like ${variablename:offset:length} so use 1 for length and give it a value of 0 through length for offset.

This also avoids needing to split on spaces, which allows people to put spaces, wildcards, and other special characters in their passwords without this choking.

Code:
N=2
pass="12345"
echo "${pass:$N:1}"
