Compare with
Deckname vs Alias
alias
'das Alias' and 'der Deckname' are both names that are not the real name. 'Alias' is the more general term for an alternative name. 'Deckname' is more specific: it is meant to hide the true identity of a person, organization, or operation. This often sounds like the police, intelligence services, security, or a secret operation. Learners can confuse the words because both refer to a false or additional name. If just another name is being used, 'Alias' fits. If the name is deliberately meant to keep something secret, 'Deckname' fits better.
