False names, or pseudonyms, are commonly used for various reasons such as anonymity, privacy, or literary purposes. Other terms that can be used interchangeably with false names include aliases, pen names, nicknames, and fake names. Aliases are frequently used in legal settings to conceal one's real identity, while pen names are commonly used by writers who want to be recognized under a different name. Nicknames are often used within friend groups or families, while fake names are usually used in situations where people do not want to reveal their true identities. Regardless of the term used, false names provide individuals with a level of discretion and control over their personal information.
