Embedded MQTT Broker Passwordfile

can someone help me with configuring the embedded mqtt broker?
what is the code for using an passwordfile and wich format must the pwfile have?

The broker embedded into HA is very simple and does not have the ability to handle different users. The one user permitted must have the same password as the HA front end.

If you need more users, you need to install a different MQTT broker. Most people here use mosquitto, but there are others available if you don’t like that.

Ok, thank. I installed Mosquitto. Works fine
