First you’ll need your streaming key as with any other platform, so log into your YouTube Creator Studio.
Click on the Go Live icon:
If you’ve not used YouTube to livestream before you’ll get this page:
You’ll need to verify your account with a phone number either via text or automated call. It does warn you that it can take up to 24 hours for it to verify, though it’s usually much quicker.
You can then choose whether you want to stream right now or schedule something in for later.
Choose your set up (auto detect microphone and camera or select your own sources) and you’ll see the stream options in a Studio screen.
You can see your stream key in the bottom left – hit Copy.
Log in as moderator and go to your meeting. Make sure you're the moderator of that session.
In the bottom of the screen, click the three dots and choose Start Live Stream
You’ll then be asked to enter your YouTube live stream key.
Paste in the key you took from YouTube and you’re ready to stream!
