A reusable stream key is created in YouTube Studio’s Live Control Room, under Create > Go Live > Stream. You then select Create new stream key, save it, and copy the key into the encoder that sends your video to YouTube.
This is the encoder workflow for software or hardware encoders, not the separate webcam-streaming workflow. The key can be selected again for later broadcasts, so you do not need to replace it in your encoder every time.
Who needs a reusable custom key
You need a custom stream key if your video is being sent to YouTube by an encoder and you want the same credential available for recurring broadcasts. This is common for a devotional channel, a lofi station, a local news loop, a study stream, or a business channel that starts similar broadcasts regularly.
An encoder may be an application running on your computer, a dedicated hardware device, or another service that sends a prepared video feed to YouTube. YouTube’s encoder guidance covers both software and standalone hardware encoder workflows.
A custom stream key is not the same thing as Reuse settings. A custom key is the credential you keep available for the encoder. Reuse settings is a shortcut for creating another stream from an earlier stream, including broader details such as metadata and settings.
| YouTube option | What it does | When to use it |
|---|---|---|
| Custom stream key | Creates a stream key that can be selected again | You want your encoder to keep using the same key |
| Reuse settings | Starts a new stream using details from an earlier stream | You want to copy previous stream information as well as its key |
| Webcam workflow | Uses YouTube’s webcam streaming route | You are streaming directly through a camera and browser, rather than an encoder |
If your main concern is avoiding repeated key changes in OBS or another encoder, create a custom stream key. If you are preparing a new YouTube broadcast and also want to copy its title, description, privacy choices, or other stream details, Reuse settings may be the more suitable shortcut.
The key itself does not create a video source. You still need an encoder with a video or audio feed, and you must follow YouTube’s normal live-streaming process before the broadcast is public. For a broader encoder walkthrough, see this guide to starting a 24/7 YouTube live stream with OBS.
Check live-stream eligibility first
Creating a key does not bypass YouTube’s live-streaming requirements. Before troubleshooting the encoder, check that the channel can live stream. YouTube says the channel must be verified and must not have had a live-streaming restriction in the previous 90 days. YouTube also says a person must be at least 16 to live stream.
The requirements concern the channel and the person operating the stream, not just the computer where the encoder runs. A key may appear in Studio, but that does not mean every broadcast will be allowed if the channel has an eligibility issue.
You can review YouTube’s current requirements in Get started with live streaming. If your channel has only just been verified, or if a restriction has recently ended, check the official page and the notices shown in YouTube Studio rather than assuming that the key will solve the problem.
It is also worth separating three different situations:
- You cannot access live streaming at all.
- You can open Live Control Room but have not yet created a stream.
- You have a stream and key, but the encoder is not sending a usable feed.
A reusable key addresses the second and part of the third situation. It does not remove an eligibility restriction, repair an encoder configuration, or provide content for the broadcast.
Open the Live Control Room Stream tab
Sign in to the YouTube channel that will own the broadcast. In YouTube Studio, select Create, then choose Go Live. When Live Control Room opens, select the Stream tab.
The wording and placement can change slightly as YouTube updates Studio, but the route is the encoder route: Create > Go Live > Stream. Do not choose the webcam route if your intention is to send a feed from OBS, a hardware encoder, or another encoder.
The Stream tab is where YouTube presents the connection information needed by the encoder. It normally includes a stream URL or server address and a stream key. The URL tells the encoder where to send the feed. The key acts as the credential YouTube uses to accept that feed.
YouTube describes stream keys as being like the password and address for a YouTube stream. Treat the two fields as separate even though they are displayed in the same area. The stream URL belongs in the encoder’s server or URL field. The stream key belongs in the encoder’s stream-key field.
If Live Control Room opens on a different tab, look for Stream before changing anything. The key-creation control belongs to this tab. The webcam flow has different controls because the browser is handling the camera connection directly.
For a 24/7 channel, it helps to decide what the encoder will send before creating the key. For example, you might have a looping MP4 file, a set of devotional videos, or a study timetable with background audio. The custom key identifies the YouTube connection, while the encoder determines what feed is sent through it.
Create a new custom stream key
On the Stream tab, find Select stream key. Open that menu and choose Create new stream key. YouTube will ask for the settings needed for the new key. Enter your preferred values, then select Create.
The key should then appear in the stream-key list. Select it when you want this key to be the one associated with the current encoder connection.
The important choice here is Create new stream key, not a generic stream setup option. If you select an existing key, you are choosing a credential that has already been created. If you create a new one, YouTube adds another key to the list.
You do not need to create a fresh key for every broadcast. The point of a custom key is that it remains available for reuse. Your encoder can retain the same key while you create or start later streams in YouTube Studio, provided you have not reset the key and the encoder is still configured correctly.
Take care if several people manage the channel. Give each key a clear name if YouTube provides a name field, so the intended use is recognisable later. A name such as “main devotional loop” or “study channel encoder” is easier to identify than several unnamed entries. Do not put the actual key in the name.
If your channel uses several encoders for different purposes, separate keys can make diagnosis easier. For example, a local news encoder and a study-loop encoder may not need to share one credential. That is an operational choice, not a requirement from the key-creation process. Fewer keys are simpler to manage, while separate keys can make it clearer which credential should be reset if one connection is exposed.
Select settings and save the key
After choosing Create new stream key, enter the preferred settings shown by YouTube and click Create. Do not assume that changing a key setting will alter the video quality of your channel. Resolution, frame rate, bitrate, audio configuration, and looping behaviour are primarily concerns for the encoder and the media it sends.
The key-creation screen is for identifying and storing the connection credential. Use the settings YouTube presents for the workflow you are configuring, and avoid copying settings from an unrelated tutorial simply because they worked for another channel.
Once created, confirm that the new key is visible in the Select stream key list. The key may be hidden until you choose to reveal or copy it. That is normal and useful: the credential should not remain openly visible while you work in a shared space or record a screen tutorial.
If you are choosing between a custom key and Reuse settings, make the decision before starting the next broadcast. A custom key is the right tool when the main requirement is a stable credential in the encoder. Reuse settings is broader because it carries information from a previous stream into a new stream, including its key. You can edit the copied stream details afterwards.
YouTube’s Manage live stream settings explains the custom-key and reuse options. Check that page if the labels in your Studio account differ, because YouTube can adjust the Live Control Room layout.
The saved key is not a public channel identifier. It is not something to add to a video description, social post, public setup guide, or screenshot. The fact that it is reusable makes careful handling more important, not less.
Copy the key into the encoder
With the custom key selected in Studio, copy it into the encoder’s stream-key field. If the encoder offers a direct YouTube connection, choose that option and follow its sign-in or connection prompts. If it asks for separate connection details, copy YouTube’s stream URL into the encoder’s server field and the stream key into the encoder’s stream-key field.
Do not swap these fields. The server field needs the stream URL. The stream-key field needs the hidden credential. A correctly copied key in the wrong field will not establish the expected connection.
After saving the encoder configuration, start the feed. Return to Live Control Room and wait for YouTube to detect the incoming signal. YouTube may show a preview or connection status before you select the control to start the public broadcast. Follow the controls shown in Studio rather than assuming that starting the encoder automatically makes the stream public.
If the encoder offers a way to store the key securely, use it rather than placing the credential in a plain text note. Keep a private record of which encoder uses which key, but do not record the full key in a document that is shared with contractors, posted in a support ticket, or synchronised to a public folder.
The first test should be long enough to expose an obvious configuration problem. Check that the picture moves, audio is present, the intended channel is receiving the feed, and the encoder remains connected after you leave the computer alone. A short test can confirm that the key was accepted, but it cannot show how the setup behaves overnight.
If you use OBS, connection recovery is a separate concern from key reuse. The OBS reconnect guide covers that part of the setup. The reusable key authenticates the encoder connection; it does not instruct OBS how to recover from a network interruption.
For audio-focused channels, check the feed separately from the key. A valid connection can still carry silence, distortion, or an unsuitable level. The guide to YouTube live audio bitrate and sample rate settings is relevant when the connection works but the audio needs attention.
Reuse the key for later broadcasts
For a later encoder broadcast, open Live Control Room, select the Stream tab, and choose the same custom key from Select stream key. Keep the matching key in the encoder. You do not need to copy a new credential just because the title, description, or video file has changed.
You may still need to create or select a new stream for each broadcast. The key and the stream are related, but they are not the same object. The key is the credential used by the encoder. The stream is the YouTube broadcast with its own title, description, visibility, schedule, and other details.
If your aim is to create a new stream based on a previous one, use Reuse settings when that is more convenient. It can carry over the previous stream’s metadata, settings, and key. Review the copied information before publishing, especially if the new broadcast has a different topic or audience.
For an always-on channel, decide whether the same stream should continue or whether you will end one broadcast and create another. Reusing the key does not by itself keep the same public broadcast running. If you need to restart a broadcast without changing its link, see the guide on restarting a YouTube live stream without changing its link.
If the practical problem is that your own computer must stay on all night, a cloud-based workflow can remove that particular burden. StreamNeo lets you upload the prepared video once, provide the YouTube stream key, and keep the channel running while your computer is switched off, with automatic monitoring and restart handling for dropped broadcasts.
That does not change YouTube’s eligibility rules or make the stream exempt from checking. You still control the channel, content, key, and YouTube Studio settings. It simply addresses the operational problem of keeping a prepared feed running without leaving a personal computer connected.

FAQ
Is a custom stream key the same as Reuse settings?
No. A custom stream key creates a reusable credential for an encoder. Reuse settings creates a new stream using information from an earlier stream, which can include its metadata, settings, and key.
Can I use this process for webcam streaming?
No. These instructions describe the encoder workflow in Live Control Room. Webcam streaming uses a different YouTube route, while this process is for software or hardware encoders that send a feed to YouTube.
Where do I put the reusable key?
Put it in the encoder’s stream-key field. If the encoder asks for separate connection details, put YouTube’s stream URL in the server field and the key in the stream-key field.
What should I do if the key is exposed?
Treat the stream key like a password. In Live Control Room, open the Stream tab, find the key, and select Reset; then copy the replacement into the encoder. YouTube says only a channel owner or manager can reset a key, not an editor or viewer.
