Morphology
The meaning 'a single key that can open or access many resources' is directly derivable from combining 'master' (primary/controlling) with 'key' (an instrument to open or grant access). The technical computing use is a clear metaphorical extension of the physical concept, so a B1 learner who knows the constituents would readily infer the MWE's meaning.
Etymology
The term master key in computing borrows that picture: imagine one digital key that can 'unlock' many files and services, like a metal key opening many doors. That's why a master key in security means one central key that can give access to many protected items.
