Default authentication behavior change:
HiveMQ CE 2020.1 only allows MQTT clients to connect if a security extension is present. For testing purposes, HiveMQ includes a hivemq-allow-all-extension (#142) that authorizes all MQTT clients to connect to HiveMQ. For proper authentication and authorization, you must add an appropriate security extension and remove the hivemq-allow-all-extension. You can download security extensions from the HiveMQ Marketplace or develop your own security extension.
