Morphology

sign + in

The meaning 'to register or record your arrival' is directly derivable from combining 'sign' (to write or affix your name) with 'in' (into/within); signing in literally means writing your name into a register or system. This verb+particle construction follows a common compositional pattern in English (and is paralleled in many other languages), so a B1 learner who knows both words will readily infer the MWE's meaning.

Etymology

Sign in comes from the simple act of writing your name in a book when you enter a place. Here, sign means to write your name and in shows you are coming inside, so the phrase came to mean 'to register your arrival'.
