The terms username, user name, and user id are ambiguous because the term user is ambiguous and may (or may not) imply that the subject linked to the digital identity is a person.
The terms username, user name, and login name are ambiguous because, in the context of authentication, the word “name” implies that the unique identifier used to authenticate is the common name of the user, which is wrong in many identity management systems.
The term login id being more generic and accurate should thus be preferred. But in practice, the other forms are in widespread usage.
