You can reuse a YouTube stream key across broadcasts. YouTube documents custom reusable keys and a separate Reuse settings workflow that carries an earlier stream’s key into a new event; its reviewed guidance does not describe “one-time stream key” as an official key type. A key is a password-like credential, so protect it and reset it if you think it has been exposed.
What a YouTube stream key does
A stream key is a credential that connects an encoder’s outgoing video feed to YouTube’s live ingest. Your encoder also needs the stream URL. YouTube describes the key and URL as: “Stream keys are like your YouTube stream’s password and address.” — YouTube Help, Manage live stream settings.
Treat the key like a password: anyone who obtains it may be able to send a feed to the associated stream. Copy it only into the encoder you intend to use, and avoid sharing screenshots or configuration files that reveal it.
Can you reuse a YouTube stream key?
Yes. YouTube documents two ways to carry a key forward: create a custom stream key for repeated use, or create a new stream by reusing the settings of an earlier stream. In the latter workflow, YouTube copies the prior stream key along with its metadata and other settings. The exact labels and available options can change, so check the current Live Control Room.

Custom reusable key
Choose a custom key from the Select stream key area in Live Control Room when you want stable encoder settings across broadcasts. Your encoder can retain that key until you change or reset it. Keep the key private, especially if more than one person has access to the encoder configuration.
Reuse settings for a new stream
When setting up another event, choose Reuse settings for an earlier stream. YouTube carries over the previous stream’s metadata, settings, and key. Review the event details before going live so the new broadcast has the intended title, description, schedule, and other carried-over settings.

What “one-time key” means here
YouTube’s reviewed key guidance does not document a separate “one-time stream key” mode. The phrase may be used informally to contrast a persistent key with creating a fresh stream event or using different credentials, but it should not be presented as an official YouTube key type.
How to connect an encoder with a reusable key
- Open Live Control Room. In YouTube Studio, create or select the live stream you plan to use.
- Choose the key workflow. Select a custom stream key for reuse, or use Reuse settings when creating a new event from an earlier stream.
- Copy both connection values. Copy the stream URL and stream key shown in Live Control Room. YouTube’s setup guidance calls for entering both in the encoder’s streaming settings.
- Enter them in the encoder. Paste the stream URL into the encoder’s server or URL field and the key into its stream-key field. Use the encoder’s own documentation for the exact field names, which vary by product.
- Start the encoder and check Live Control Room. Confirm YouTube receives the feed and that the selected event is the one you intended before proceeding with the broadcast.
RTMP or RTMPS: choosing a secure connection
YouTube describes RTMPS as RTMP carried over a TLS/SSL connection. To use it, your encoder must support RTMPS and be configured with the RTMPS stream URL. If the encoder offers an RTMPS preset, select it; otherwise, copy the RTMPS URL from Live Control Room and enter it with the stream key. A key by itself does not switch the connection to RTMPS.

Check the URL and protocol supported by your encoder rather than assuming every encoder offers the same transport options. YouTube’s explanation is in YouTube Help’s RTMPS guidance.
When to reset a stream key
If you believe someone else has seen or obtained the key, reset it in YouTube Studio’s Live Control Room and replace the saved value in your encoder. YouTube says a channel owner or manager can reset the key.

- Open YouTube Studio and go to Live Control Room.
- Select Stream and find Stream key.
- Choose Reset and copy the newly generated key.
- Replace the old key in the encoder’s streaming settings, then verify that the encoder connects using the updated value.
Resetting invalidates the old saved credential for future connection attempts, so update every encoder configuration that relies on it. YouTube also recommends getting a new key and updating the encoder for certain encoder start errors; follow the error-specific guidance rather than assuming every connection problem is caused by a compromised key.
Common connection problems and fixes
- The encoder cannot connect: Check that both the stream URL and key were copied from the intended stream, and that each was pasted into the correct encoder field.
- You recently reset the key: Replace the old saved key in the encoder. A reset key will not match an encoder still using the previous value.
- You selected RTMPS but the encoder fails: Confirm the encoder supports RTMPS and that the URL is the RTMPS URL from Live Control Room, not a different protocol’s URL.
- You reused an earlier stream and the event details are wrong: Review the new stream’s carried-over metadata and settings before going live, then edit what needs to differ.
- An encoder start error persists: YouTube’s guidance recommends obtaining a new key and updating the encoder for certain start errors. Check the specific error’s instructions and confirm the encoder is using the replacement key.
Does reusing a key require a hardware encoder?
No special hardware is required just to reuse a key. YouTube recommends professional-grade hardware encoders for events that need higher production value, but that is a production choice—not a condition for key reuse. Whatever encoder you choose must be configured with the stream URL and key, and must support the transport you plan to use.
