Key Differences
An alias is typically used to conceal one's identity, perhaps for privacy or legal reasons, or in fictional settings. In contrast, a nickname is a name given in affection, often based on personal characteristics or inside jokes.
Alias usage can be for professional purposes, such as authors using pen names, or for privacy by celebrities. Nicknames, however, are often used informally among friends, family, and colleagues.
An alias may have no relation to the person's real name and can be completely made up. A nickname usually derives from one's real name or personal traits, simplifying or modifying the original name.
While an alias is often adopted to separate one aspect of a life from another, nicknames are integrated into all aspects of one’s life, reflecting familiarity and affection.
Using an alias might require legal documentation if used for official purposes, whereas a nickname can be adopted and dropped casually without any formal process.
