Well, IMO the definition of the word "anonymous" still fits how personal information is handled in Briefing: "Anonymity describes situations where the acting person's name is unknown" [1] And this is true regarding the Briefing service.

Heh, well you cherry-picked there. It goes on to say ". The important idea here is that a person be non-identifiable, unreachable, or untrackable."

Regardless, it's Wikipedia, that definition ought to be fixed to say "identity" rather than "name".

For online transactions, "name" has been generalized to PII (Personally Identifiable Information) from which name can often be derived.

An anonymous user is precisely the one who hasn't provided authentication credentials

> Anonymous User is any user who accesses network resources without providing a username or password.

Se anonymous is correct in this context
