MQTT password length

[mcmuller]

Hi all,

I integrated the LoRaWan soil-moisture-sensor solution from opensprinkler.de (running just fine!) and ran into problems connecting to TheThingsNetwork mqtt-server, which requires a 98-characters-long generated API-key as password. Connecting to my own MQTT is fine, so I guess it’s the PW-length. Can soeone confirm or point me to a solution?

The maximum length of MQTT user name and password are both 32:

It’s certainly possible to increase these further, but 98-character password? That seems excessively long. Is that even necessary?

Hi Ray,
it’s a token from TheThingsNetwork….
