Morphology

sign + on

The combination of 'sign' (to register or mark agreement) and 'on' (indicating joining or being active) gives a plausible cue that this involves registering or joining a service, so learners may infer a general sense of entering or joining. However, the precise computing meaning—authenticating by entering credentials—is a metaphorical extension from physical signing and not strictly derivable from the literal senses, so it is only partially predictable.

Etymology

Sign on comes from the simple act of writing your name on a paper or a list to show you agree to join, for example signing a job contract or a ship's crew list. That's why sign on means 'to agree to start work or join an organization'.
