What Does Screen Name Mean?
A screen name is simply a name that a user chooses to represent him or herself when using some application. It could be a social media site, an instant messaging application or some other kind of collaborative application. While many screen names are pseudonymous, some services require users to use their real names. This is controversial because users often want to maintain their privacy, but real name policies might make them less safe.
