Morphology

secret + code

The meaning is directly and transparently built from 'secret' (hidden/kept private) combined with 'code' (a system of symbols or an access/password): a code that is secret for access. This compositional pattern is common and cross-linguistically familiar, so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Secret code comes from the idea of people changing normal words into special signs so others cannot read the message. Here secret means hidden and code means a set of signs, so it now means 'a hidden way to write or send a message'.
