YouTube Stream Key: Find, Reset and Reuse It

Where to find your YouTube stream key in the Live Control Room, how to reset or reuse it, RTMP vs RTMPS, and YouTube's published encoder settings.

Where to find your YouTube stream key

YouTube creates the key for you inside the Live Control Room. According to YouTube Help, to create a stream you go to YouTube Studio, click Create then Go Live to open the Live Control Room, and open the Stream tab. If it is your first live stream, you edit your stream and click Create stream; if you have streamed before, your previous stream settings load, including your stream key, so you do not need to update your encoder. YouTube also says that enabling live streaming for the first time may take up to 24 hours.

In your encoder, choose YouTube if it is listed. Otherwise copy the stream URL from YouTube into the encoder's server field (it may say RTMP server) and copy the stream key into the Stream Key field. Start the stream from your encoder, wait for the preview in the Live Control Room, then click Go live (unless auto-start is on).

What YouTube says about stream keys

YouTube describes stream keys as "like your YouTube stream's password and address": they tell your encoder where to send your feed and let YouTube accept it. YouTube Help explains two ways to reuse a key:

  • Reuse settings. A new stream created with Reuse settings copies the previous stream's metadata, settings and stream key.
  • Custom stream key. Under Select stream key, click Create new stream key, enter your settings and click Create; the key then appears in your stream key list and can be reused.

How to reset a YouTube stream key

If your key is compromised, YouTube Help gives these steps: go to YouTube Studio, click Create then Go Live, select the Stream tab, find the Stream key section, click Reset next to the hidden key, copy the newly generated key and update your encoder software. YouTube notes that you must be a channel owner or manager to reset a stream key; editors and viewers do not have this permission.

Stream URL: RTMP and RTMPS

YouTube shows a Stream URL to enter in the encoder. Its RTMPS help page says YouTube recommends encrypting your stream with RTMPS, that the Live Control Room shows the RTMP URL by default and the lock icon next to it reveals the RTMPS URL, and that if you get an SSL error you can try specifying port 443 in the URL (or in your encoder's port field). It gives the form rtmps://exampleYouTubeServer.com:443/stream as an example and tells you to use the real Stream URL from your Live Control Room.

Frequently asked questions

Where is my YouTube stream key?
In YouTube Studio: Create, Go Live, then the Stream tab of the Live Control Room, in the Stream key section.
