A name alias is an alternative name used by an individual in addition to their given name. This alias can be used for various reasons, such as privacy, security, or personal preference. Some people may use aliases online to protect their identity, while others may use them in professional settings to create a distinct persona. Name aliases can also be used in creative works, such as writing or performing arts, to establish a unique identity. Overall, a name alias allows individuals to separate different aspects of their lives or personas under different names.
