This saves you from creating a new encoder credential each time, but it does not keep a broadcast running by itself or make one live event permanent. For a recurring channel, the encoder and stream workflow must also be running and monitored.
What a reusable stream key does—and does not do
YouTube describes a stream key as an encoder credential: it tells the encoder where to send its feed and lets YouTube accept it. A custom key can be selected again for later broadcasts. Treat it like a password; anyone who obtains it may be able to send a feed to your channel. YouTube’s instructions are in Manage live stream settings.
A reusable key is not a permanent live event. It does not keep your encoder, computer, or network operating, automatically restart a stopped feed, preserve one watch page forever, or guarantee that every broadcast is archived. YouTube’s setup guidance does not establish a universal maximum live runtime or promise indefinite uptime.
Create a custom key in Live Control Room
- In YouTube Studio, select Create → Go Live, then open the Stream tab.
- Open the stream-key selector and choose the option to create a custom stream key.
- Enter the preferred settings, save the key, and keep it private. Labels and interface details can change; follow the current controls shown in Live Control Room.
- In your encoder, enter YouTube’s stream URL/server and the custom stream key. Select the desired video and audio sources and configure the encoder’s output.
- Start sending the feed from the encoder. For a scheduled stream, wait for the preview in Live Control Room, check that it looks and sounds right, then select Go live as directed in YouTube’s encoder setup instructions.
Before relying on the setup, check the Live Control Room preview and stream health, confirm that viewers can access the stream from the channel or watch page and on mobile, and verify that any local recording is being saved. YouTube recommends monitoring audio and video continuously; see YouTube’s live-streaming tips.

Choose between reusing the key and reusing stream settings
These are related but separate workflows. Keep the custom key selected in your encoder when you want the same encoder credential for recurring sessions. Use Reuse settings when you want to create a new stream with a previous stream’s metadata, settings, and stream key copied over. In Live Control Room, the reuse action is in the Manage tab: select the prior stream and choose Reuse settings. Review the copied title, description, privacy, and other details before starting; copying settings does not turn the previous event into a permanent one. See Manage live stream settings.
| Workflow | What carries over | Best fit |
|---|---|---|
| Keep a custom key selected in the encoder | The reusable encoder credential | Recurring sessions where you want the encoder configuration to persist |
| Choose Reuse settings for a previous stream | Metadata, settings, and the stream key | A new stream when you want to begin with a prior event’s setup |
Plan for an always-on channel, not just a reusable key
If by “always-on” you mean a channel that broadcasts repeatedly, a custom key can simplify the encoder side, but you still need an operating plan for starting sessions, checking that YouTube receives the feed, and responding if the encoder or connection stops. Confirm how your encoder handles restarts and whether your YouTube workflow requires a new event or watch page. A saved key alone does not answer those questions.

If you mean one uninterrupted event, distinguish that from a repeating schedule. YouTube warns that streams longer than 12 hours may not be captured at all and that DVR may be limited or unavailable beyond 12 hours. These are archive and viewer-seeking cautions, not a statement that YouTube universally ends a stream at 12 hours.
- Archive: YouTube says streams shorter than 12 hours can be automatically archived, but a stream exceeding 12 hours may not be captured at all. Keep a local recording if the complete replay matters. See Archive live streams.
- DVR: Viewers may not be able to rewind as expected on a very long broadcast; YouTube says DVR may be limited or unavailable for streams longer than 12 hours. See Turn on DVR on live streams.
Protect the key and recover if it is exposed
Do not publish the key in a screenshot, chat, public configuration file, or stream description. If you believe it has been exposed, reset it in Live Control Room and replace the old value in the encoder before the next broadcast. YouTube says channel owners and managers can reset a key; editors and viewers cannot. Resetting changes the credential, so an encoder still using the old key will no longer send with it. See Manage live stream settings.

Troubleshoot common reuse problems
- YouTube does not receive the feed: Check that the encoder has the correct YouTube stream URL/server and the currently selected key, then confirm that the encoder is actually sending. If the key was reset, update the encoder with the replacement.
- The preview appears, but the stream is not public: For a scheduled stream, check the preview and use Go live in Live Control Room when required. Also verify the event’s privacy and schedule settings.
- The wrong title or privacy setting appears on a later session: If you used Reuse settings, review the copied metadata and privacy before starting the new stream.
- The live stream stops unexpectedly: A reusable key does not restart the encoder or restore a failed network connection. Check the encoder and connection, then confirm the feed and stream health in Live Control Room before relying on the broadcast again.
- The replay is missing or viewers cannot rewind far enough: For streams exceeding 12 hours, YouTube warns that archive capture may fail and DVR may be limited or unavailable. Use a local recording when preservation matters.
