the.com/alias

The name you use when your real one has too much baggage.

means An alternative name someone goes by, often to hide or separate their identity from their real one.

from From Latin 'alias', meaning 'at another time, otherwise' — itself from 'alius', meaning 'other'. It started as an adverb lawyers and clerks used to say 'otherwise called' when listing someone's other names, and over time the word hardened from a linking phrase into the name itself.
