In the past it was possible to configure multiple users and passwords in the MQTT broker.
This looks gone.
I used it because I had a device that had requirements on the password that didn’t match with my default setup so I added a second user and password but can’t find this back.
Not sure with what version is was removed.
Ach ok thanks. Indeed it is still in the add-ons but it is confusing. Mqtt is now also part of the integrations and in the configuration at that place you only seen one userid and password.
