user name
     
         or "logon" a unique name for
        each user of computer services which can be accessed by
        several persons.
     
        users need to identify themselves for accounting, security,
        logging, and resource management.  usually a person must
        also enter a password in order to access a service.  once
        the user has logged on the operating system will often use a
        short user identifier, e.g. an integer, to refer to them
        rather than their user name.
     
        user names can usually be any short string of alphanumeric
        characters.  common choices are first name, initials, or some
        combination of first name, last name, initials and an
        arbitrary number.  user names are often assigned by system
        administrators according to some local policy, or they may be
        chosen by the users themselves.
     
        user names are often also used as mailbox names in
        electronic mail addresses.
