              <dd>
                Choose if keyboard-interactive authentication is available.
                This authentication method is used to log in to the server by using your password 
                that has disabled password authentication such as FreeBSD. <br>
                Encrypted input data are sent to the server with the method.
                When a password is input for authentication, same as password authentication,
                encrypted password passes through.

      <dd>
        Modified to confirm the available authentication method for the server prior to login and invalidate unsupported method.<br>
        Modified to access the server by using only user name in background when displaying authentication dialog. In order for this feature to work, user name must be identified when a connection request is started. If user name is specified in a default user name or in a command line, it will be used.<br>
        If a focus is lost after user name is entered, a content of user name field is used and it can't be changed afterward.
