If OBS is not using the custom YouTube stream key you expect, first check which setup path is active. In OBS, open Settings > Stream and confirm whether OBS is connected to your YouTube account or configured for manual stream-key entry. To reuse a particular key, select that custom key in YouTube Studio and use the key-entry workflow in OBS. These are distinct configuration paths; the available documentation does not establish that OBS universally replaces custom keys or identify one cause for every report.
Check whether OBS is connected to YouTube or using a manually entered key
Open OBS > Settings > Stream. Confirm the service or destination is YouTube, then identify whether the page shows a connected YouTube account or the controls for entering a stream key. OBS documents both selecting a streaming service or custom server and entering a key in Stream settings: OBS: Streaming with OBS Studio.

The connected-account workflow and manual key entry are not interchangeable. With account connection, OBS integrates with YouTube for broadcast setup. If you specifically need OBS to use a key you selected in YouTube Studio, use the key-entry path available in the current OBS service settings and enter that selected key. OBS exposes account connection separately from stream-key controls, but that distinction alone does not prove account connection caused a key change on your computer: OBS: Connecting Your Accounts.
Create or select the custom key in YouTube Studio
- Open YouTube Studio and go to the Live Control Room.
- Open the Stream tab and choose Select stream key > Create new stream key to create a custom key.
- Select that custom key for the stream you intend to run. YouTube supports reusing a custom stream key.
- In OBS, open Settings > Stream, choose the key-entry setup, and enter the selected YouTube key. Save the settings and verify the destination before going live.
YouTube describes stream keys as “like your YouTube stream’s password and address”: they tell the encoder where to send the feed and allow YouTube to accept it. Follow YouTube’s steps in Manage live stream settings.

Back up the OBS profile before changing settings
Before switching workflows or editing the key, duplicate or export the current OBS profile. OBS profiles include Stream settings and connected-account information, so a backup gives you a rollback point if the new configuration does not work. See OBS: Profiles.
If you reset the key, update OBS with the new one
If the key was reset or may have been exposed, use YouTube Studio’s documented reset path: YouTube Studio > Go Live > Stream tab > Reset beside the hidden key. Copy the new key and update the encoder software using it. Do not keep trying the old key after a reset; YouTube’s instructions are in Manage live stream settings.

What to record if the key still appears to change
The official setup guidance supports checking the workflow and key selection, but does not establish a universal OBS replacement behavior, a single cause, or a confirmed bug for an unspecified OBS version. To narrow down an individual case, note:
- Your OBS version and operating system.
- The selected service or destination in Settings > Stream.
- Whether the YouTube account is connected or a key is manually entered.
- Exactly when the value changes—for example, after changing a setting, reopening OBS, or starting a stream.
- A redacted OBS log, with the stream key removed.
Treat the key like a password. Never include the actual key in a public post, screenshot, or support report.
