Morphology

passphrase = pass + phrase (transparent) = pass + phrase

The word is a straightforward compound of 'pass' (in the sense of password/credential) + 'phrase', meaning a phrase used as a pass; the meaning is directly derivable.

Etymology

The word passphrase combines pass (as in password) and phrase, which means 'a small group of words'. So a passphrase is like a longer, sentence-style 'password' used to protect access.
