Setting up Blue Iris Integration in HA, where's my USERNAME and PASSWORD

I have BLUE IRIS running as a service on my main PC. I’ve installed the BI in HACS and also installed the integration, however, I keep getting “Invalid Server Details.” I have the correct IP address, 192.168.0.70 and the port is 81, but NONE of my usual usernames and passwords work. What am I missing? or where can I find this information?
