Only one MQTT user is available for each user and it is your registered e-mail address.
Currently topics start with MQTT user name (registered e-mail address) as a prefix.
After virtualization, each user will have his/her own working container.
All topics have both R/W permissions.
Port numbers are fixed for each user and they are 1883 for TCP and 8883 for Websocket.
Temporarily, there is no TLS support. Will be added for MQTT connections.
Created topics are not able to be removed.
Google and FB login will be activated soon.
