Approved to stream with TikTok Live Studio. I want to multistream with OBS, is it worth it?

I have 15k on TikTok and was just approved to use The Live Studio Desktop app. I'd like to maximize my efficiency by streaming on multiple platforms at once. I've streamed on YouTube in the past and prefer it to Twitch, but will stream on all three if possible.

I started setting everything up with Aitum's Multistream and Vertical plugins, but when I got to the part where I need to enter my Server and Stream Key, I cannot find them anywhere for TikTok. Upon some research, I'm seeing something about Agencies being needed to gain access, but I'd rather not do something sketchy like that. I also saw there were ways to generate Stream Keys with third party software but don't want to risk getting shadowbanned (unless they're proven to be safe).

Could I just hypothetically stream an instance in OBS for YouTube/Twitch, and at the same time stream an instance in TikTok Live Studio? It would be the same content, but just not the same "stream" I suppose? Sorry if I'm not super clear.

What is the downside to running two separate instances, one being in OBS for Twitch/Youtube, and the other being for TikTok Live Studio? I can at the very least ensure I won't be upsetting TikTok, right?

My latest speed test:

• Download Speed: 810.4 Mbps
• Upload Speed: 202.4 Mbps
• Latency: 7 ms

So I don't think connectivity would be the issue, my hardware is decent too. Is it worth the hassle to try and get a stream key to keep everything standardized/refined in one area (OBS)? Or should I do as I suggested above and run two separate streams?

Thank you!
