[Mosquitto] How to find passwords for homeassistant and addons users?

[mahnunchik]

Describe the issue you are experiencing

https://github.com/home-assistant/addons/blob/master/mosquitto/DOCS.md#home-assistant-user-management

According to the documentation homeassistant and addons users are pre-registered. I'd like to use mqtt-io addon with Mosquitto broker. Since this is an addon, it makes sense to use the existing addons user for it.

How to find passwords for homeassistant or at least addons user?

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Which add-on are you reporting an issue with?

Mosquitto broker

What is the version of the add-on?

6.4.1

Steps to reproduce the issue

1. Install Mosquitto broker
2. Install MQTT IO
3. I'm shocked that the addon can't connect...

Anything in the Supervisor logs that might be useful for us?

No response

Anything in the add-on logs that might be useful for us?

No response

Additional information

Maybe there is some predefined user/pass that can be used in mqtt-io config?

/homeassistant/mqtt-io/config.yml

mqtt:
  host: homeassistant.local
  topic_prefix: mqtt_io
  user: homeassistant #OR addons
  password: #?????????????????
  ha_discovery:
    enabled: yes

I found that Mosquitto broker publishes the connection details. I have two questions:

• How can I found this user/pass?
• Is it possible that MQTT-IO can utilize this details?
