It is very common to have to identify yourself in order to gain access to a network or private web site.
You do this by providing an 'username' and a password. The username is your identity on that particular network. When you first set up an account on the network, you are asked to provide an username. Sometimes the administrator will assign you an username instead.
You can have many usernames across many networks and websites.
