Shorter Username & Password

Hi Guys,
I’m trying to leverage the built-in MQTT stack inside a U-Blox SARA-R4 NB-IOT module. However, The max length for the username and password is 30 characters each. Right now, the “My Devices - Cayenne” username is 36 chars and the password is 40 and this is auto-generated and seemingly unchangeable. Is there any way to generate a shorter username and password for a Cayenne application?


the MQTT credentials cant be made shorter right now.
