You need to specify the password in the configuration file as follows

[--redis|-r] <fmt>                  | Redis connection. <fmt> is specified as
                                    | [h[:port[:pwd]]][@db-id] where db-id
                                    | identifies the database Id (default 0).
                                    | h is the host running Redis (default
                                    | localhost), optionally followed by a
                                    |  ':'-separated port (default 6379).
                                    | The special characters \ and ` are not
                                    | supported by ntopng.
                                    | A password can be specified after
                                    | the port when Redis auth is required.
                                    | By default password auth is disabled.
                                    | Examples:
                                    | -r @2
                                    | -r 129.168.1.3
                                    | -r 129.168.1.3:6379@3
                                    | -r 129.168.1.3:6379:nt0pngPwD@0

or remove the authentication and ntopng will start
