Do I need a dual connection to access the API from multiple machines?

I am building an application that will need to connect to the Tradovate API from 2 different machines: one to stream in candlesticks / trades, another machine to place trades. Do I need to purchase the Dual connection add on on Tradovate to allow this? How about if I want to be logged into tradovate web at the same time?

Does anyone know the answer to this?
After enabling API access - do you need to purchase dual connection even for logging into the web? Or with just one connection - you can place trades via API and also login into web at same time?
