Changing Mosquitto homeassistant password

I have been using the built in MQTT broker for home assistant for the past couple years and now with the update, it has been deprecated.

I want to switch to Mosquitto for the broker however Mosquitto won’t allow you to change the user: “homeassistant” password. The documentation says it doesn’t allow the “homeassistant” user to be configured in the addon settings as it already configures that user automatically. How can I change that users password, as all my MQTT devices are wanting to login with the “homeassistant” username for MQTT.

Yes I should of possibly had multiple MQTT accounts for each device but…

Hope you can help!

I don’t think you can create multiple users on a mqtt device.
