PubSubClient.connect with userName/password ?

[dpapdpap]

I can't connect to my MQTT server because it wants to login but PubSubClient.connect hasn't this ability.
Know someone what can I do, please ?

You use the set_auth method on MQTT::Connect:

PubSubClient client(wifiClient, server_ip, port);
client.connect(MQTT::Connect("some_id_string").set_auth("username", "password"));
