[Star Wars] Echo got his nickname for repeating orders, Fives got his nickname because of his birth number, why did Cody get his?

There's a scene in *Rebels* where Rex mentions that the Empire was still using security codes that he and Cody came up with during the Clone Wars - maybe Cody was really good with codes. *Code*-y.

Or maybe he just really liked the name Cody. ¯\\\_(ツ)_/¯
