Hi @zqb666 - It depends on how the broker authorization is setup but for simple auth:

final Mqtt5BlockingClient client = Mqtt5Client.builder()
                        .identifier(getClientId())
                        .serverHost(HOST)
                        .serverPort(PORT)
                        .simpleAuth()
                            .username(USERNAME)
                            .password(ByteBuffer.wrap(PASSWORD.getBytes(StandardCharsets.UTF_8)))
                        .applySimpleAuth()
