+In SSH-2, it is possible to establish a connection without using SSH's
+mechanisms to identify or authenticate oneself to the server. Some
+servers may prefer to handle authentication in the data channel, for
+instance, or may simply require no authentication whatsoever.
+
+By default, PuTTY assumes the server requires authentication (most
+do), and thus must provide a username. If you find you are getting
+unwanted username prompts, you could try checking this option.
+
+This option only affects SSH-2 connections. SSH-1 connections always
+require an authentication step.
