double identity

Two lives lived

A double identity is a person's maintenance of two separate personas, typically with one concealed from most people.

The term appears in discussions of superheroes who live ordinary lives, spies operating under cover, or anyone leading a secret parallel existence: He maintained a double identity for years—respectable accountant by day, card shark by night.

The phrase emphasizes deliberate compartmentalization rather than mere complexity of character.
