unique identity
One-of-a-kind character
A unique identity is the distinct combination of characteristics that makes a person or thing distinguishable from all others.
In personal contexts, it refers to the qualities, experiences, and traits that define who someone is: She struggled to maintain her unique identity after the merger.
In technical contexts—databases, authentication systems, digital records—a unique identity is an identifier guaranteed to correspond to exactly one entity: Each user receives a unique identity in the system.
