Connect your OBS account to Twitch in three steps

Open OBS Studio on your computer. In the bottom right corner, you'll see a button labeled "Connect Account" or a settings icon next to "Twitch" — the exact location depends on your OBS version, but both lead to the same place. Click it, and OBS will open your web browser to a Twitch login page. Sign in with your Twitch username and password, then click "Authorize" when Twitch asks permission for OBS to broadcast on your behalf. Close the browser tab and return to OBS — you should now see your Twitch channel name displayed in the bottom right, confirming the connection worked.

If you don't see a "Connect Account" button, your OBS version may be older. Update OBS from obsproject.com to the latest release, then restart the program and try again. The connection process is the same across Windows, Mac, and Linux.

Once connected, you can start streaming by clicking the "Start Streaming" button in OBS. Your broadcast will go live on your Twitch channel when ready. Viewers will see your stream appear on your Twitch page and in the "Live" section if they follow you.

Key Takeaways

  • OBS connects to Twitch through your web browser — you sign in once, and OBS remembers the connection for future streams.
  • The "Connect Account" button is in the bottom right corner of OBS, next to where it shows your Twitch channel name after connection.
  • You must authorize OBS to broadcast on your Twitch account; Twitch will ask for this permission the first time you connect.
  • After connecting, you control what viewers see through OBS scenes and sources — Twitch receives only the video and audio you send from OBS.

What happens when you click "Authorize" on Twitch

When you click "Authorize," you're giving OBS permission to start and stop broadcasts on your Twitch channel without asking you again. Twitch generates a unique code that OBS stores on your computer. This code tells Twitch "this is OBS, and this person said it's okay to broadcast." You only do this once — the next time you open OBS, it already has the code and connects automatically.

This is different from giving OBS your actual Twitch password. You never type your password into OBS itself. If you ever want to revoke this permission — for example, if you're using OBS on a shared computer — you can go to your Twitch account settings under "Connections" and disconnect OBS from there. After that, OBS will ask you to authorize again the next time you try to stream.

Checking that the connection is working before you go live

After connecting, look at the bottom right of OBS. You should see your Twitch channel name displayed next to the streaming controls. If you see your channel name, the connection is active. If you see an error message or a "Connect Account" button still visible, the authorization didn't complete — go back and try the process again.

Before you start streaming to an audience, click "Start Streaming" and watch OBS for 10 to 15 seconds. Check that the "Streaming" indicator shows a green light or "Active" status. Then stop the stream by clicking "Stop Streaming." This test run confirms that OBS can actually send video to Twitch, which catches problems like incorrect bitrate settings or network issues before you broadcast to viewers.

What OBS sends to Twitch, and what stays on your computer

OBS sends only the video and audio you've arranged in your scenes — nothing else on your computer is visible to Twitch or your viewers. If you have a web browser open behind OBS, or files on your desktop, or a second monitor with private information, none of that appears in the stream. Only what you've added to OBS scenes gets broadcast.

Your microphone, webcam, game window, or screen share — whichever sources you've added to OBS — are what Twitch receives. You control exactly what goes into each scene. If you want to hide something before streaming, remove it from the scene or mute the audio source in OBS. Everything else on your computer stays private.

Fixing common connection problems

If OBS won't connect to Twitch, the most common cause is an outdated version of OBS. Check obsproject.com for the latest release, read it, and install it over your current version. Restart OBS and try connecting again.

If you see an error message during authorization, clear your web browser's cookies and cache, then try the connection process once more. Sometimes a stale login session in your browser prevents Twitch from recognizing you.

If OBS connects but says "Failed to connect to server" when you click "Start Streaming," your internet connection may be too slow for the bitrate you've set. In OBS, go to Settings > Output and lower the bitrate from 6000 to 4000 or 3000, then try streaming again. A lower bitrate means lower video quality, but it will stream reliably on slower connections.

If none of these steps work, restart your computer and your internet router. Wait 30 seconds after restarting the router before opening OBS. This clears temporary connection problems that sometimes prevent OBS from reaching Twitch's servers.

What to do if you want to stream from a different computer

If you set up OBS on one computer and later want to stream from a different one, you'll need to authorize OBS on the new computer. The process is identical: open OBS, click "Connect Account," sign in to Twitch, and click "Authorize." Each computer gets its own authorization code, so you can stream from multiple machines without any conflict.

If you're moving to a new computer permanently, you don't need to do anything on the old one. Just set up OBS on the new computer and authorize it. The old authorization will still exist in Twitch's records, but it won't cause problems — Twitch allows multiple devices to be authorized at once.

Frequently Asked Questions

Do I have to use OBS to stream to Twitch?

No. Twitch has a built-in browser-based streaming tool, and other software like Streamlabs, XSplit, and Lightstream also connect to Twitch. OBS is free and widely used, but it's not required. Choose whichever software fits your setup and comfort level.

Can someone else use my OBS authorization to stream on my channel?

Only if they have access to your computer. The authorization code is stored locally on your machine, not in the cloud. If you're concerned about security, you can revoke OBS's access from your Twitch account settings under "Connections," and then authorize it again on your own computer.

What if I forget to disconnect OBS before lending my computer to someone?

If someone else uses your computer while OBS is authorized, they could start a stream on your channel. Revoke the authorization when ready from your Twitch account settings, then reauthorize OBS on your own computer. This removes the old code and creates a new one that only works on your machine.

Does OBS need internet to work, or just to connect to Twitch?

OBS needs internet only when you're streaming. You can set up scenes, add sources, and adjust settings offline. When you click "Start Streaming," OBS connects to Twitch and sends your broadcast. If your internet drops during a stream, OBS will try to reconnect automatically, but your viewers will see the stream end.

Can I stream to Twitch and another platform at the same time with OBS?

Yes, but you need to set it up in OBS settings under "Stream." Instead of selecting "Twitch" as your service, choose "Custom" and enter the streaming URL and key for the second platform. This is called multi-streaming. Be aware that streaming to multiple platforms uses more of your internet bandwidth, so you may need to lower your bitrate.
