You can find it in the theme you are using. The file is called login.tpl. For example for persona its here. https://github.com/NodeBB/nodebb-theme-persona/blob/master/templates/login.tpl#L15

The server sends in the value depending on what the ACP setting is set to. If you only allow login by username that value changes to Username etc.
