OneStream’s guide to connecting multiple social accounts in Studio documents choosing connected accounts as destinations. If your goal is to stream to both YouTube channels at once, select both as destinations and verify that both appear before starting. The guide describes selecting multiple social accounts but does not specify a YouTube-only limit or guarantee that every workflow permits two YouTube destinations simultaneously.
Choose destinations for an encoder stream
If you send video from OBS or another encoder rather than OneStream Studio, use the encoder destination workflow:
-
Open Encoder Streaming and select a stream key if one is needed.

-
Check the session’s destination selector. In Studio, open Set Destinations; for an encoder broadcast, use its separate Set Destinations flow.
-
Ask OneStream support if it remains unavailable. The published guides explain how to add and select accounts, but do not establish a maximum number of separate YouTube accounts that can remain connected in every workflow.
Account connections and plan destination limits are different
OneStream’s multistreaming page, accessed October 3, 2026, advertises simultaneous destination capacities of 2 on Free, 5 on Basic, 10 on Standard, 30 on Professional, and up to 50 on Enterprise; it also says accounts are available as add-ons. These are advertised simultaneous-destination capacities, not a stated cap on how many separate YouTube accounts can stay connected. Plan names and limits can change, so check the current OneStream multistreaming page for your plan. The reviewed setup documentation does not establish that connecting a second YouTube account itself requires a paid plan.
