Your stream key is a unique code Twitch gives you to connect your broadcasting software to your channel
A stream key is a long string of characters that tells your broadcasting software (like OBS Studio, Streamlabs, or XSplit) where to send your video and audio. Without it, your software has no way to know which Twitch channel to stream to. Think of it like an address — your software needs to know exactly where to deliver your broadcast.
Twitch generates this key automatically when you create a channel. You do not need to request it or do anything special — it already exists. You just need to know where to find it and how to use it safely.
Key Takeaways
- Your stream key lives in your Twitch Creator Dashboard under Settings, then Stream, then Primary Stream Key.
- You should treat your stream key like a password: never share it publicly, never paste it in chat, and never show it on screen during a broadcast.
- If you think someone has seen your stream key, you can reset it immediately from the same Settings page, and a new one takes effect right away.
- Different broadcasting software asks for your stream key in different places, but they all need the same information from your Twitch account.
How to locate your stream key in the Creator Dashboard
Log into Twitch and go to your Creator Dashboard. You can find this by clicking your profile icon in the top right corner and selecting "Creator Dashboard" from the menu. Once you are there, look for "Settings" in the left sidebar — it is usually near the bottom of the menu.
In Settings, click "Stream" in the left menu. You will see a section called "Primary Stream Key" with a long string of letters and numbers hidden behind dots for privacy. Click "Show" to reveal the full key. This is the code you need to paste into your broadcasting software.
Entering your stream key into broadcasting software
The exact steps depend on which software you use, but the concept is the same everywhere. You are looking for a field labeled "Stream Key", "Streaming Key", "RTMP Key", or sometimes just "Key".
In OBS Studio, go to Settings, then Stream. Set the Service to "Twitch", then paste your stream key into the "Stream Key" field. In Streamlabs, click the settings icon, go to Stream, and paste it into the designated field. In XSplit, go to Broadcaster Settings, find the Stream Key field, and paste it there. Most software will also ask you to select "Twitch" as your platform so it knows how to format the connection.
After you paste your key, do not close the software — leave it there. Your software will use it every time you start a broadcast, so you only need to enter it once.
Why you should keep your stream key private
Your stream key is essentially a password to your broadcast. If someone else has it, they can stream to your channel without your permission. They could broadcast inappropriate content, spam, or anything else to your audience while your channel name is attached to it.
Never share your stream key in chat, on social media, in Discord servers, or anywhere public. Never show it on screen during a broadcast — if you are recording a tutorial or taking a screenshot, make sure the key is hidden or blurred. If you are working with a streaming service or moderator who needs to help you set up, you can share it privately, but assume anyone who sees it could misuse it.
What to do if your stream key has been exposed
If you think someone has seen your stream key — whether you accidentally showed it on stream, pasted it in the wrong place, or shared it with someone you no longer trust — you can reset it immediately. Go back to Creator Dashboard, Settings, Stream, and look for a "Reset Stream Key" button or link next to your current key. Click it, and Twitch will generate a brand new key.
The new key takes effect right away. Your old key stops working instantly, so anyone who had the old one can no longer stream to your channel. You will need to update your broadcasting software with the new key — just paste the new one into the same field where the old one was. This usually takes less than a minute.
Troubleshooting when your software will not connect
If you have entered your stream key but your software says it cannot connect, the most common cause is a typo or extra spaces. Copy your key directly from Twitch instead of typing it by hand. Make sure you have selected "Twitch" as your platform in your software — some software defaults to a different service.
Check that you are using the Primary Stream Key, not a secondary one (if you have set up multiple keys). Restart your broadcasting software after entering the key. If you are still having trouble, try resetting your stream key from the Twitch dashboard and entering the new one into your software.
Secondary stream keys and when you might need them
Twitch lets you create secondary stream keys if you want to stream from multiple devices or software at the same time, or if you want to give someone else a key without sharing your primary one. You can find the option to add a secondary key in the same Stream settings page where your primary key lives.
Most streamers never need a secondary key. You only need one if you are running two separate broadcasts simultaneously (which Twitch allows) or if you want to revoke access for one person without resetting your main key. If you do create a secondary key, treat it with the same privacy you would give your primary key.
Frequently Asked Questions
Can I use the same stream key on multiple devices?
Yes, you can use your primary stream key on as many devices as you want, but only one broadcast can be active at a time. If you try to stream from two devices simultaneously using the same key, Twitch will stop the first broadcast and start the second one. If you need to stream from multiple devices at once, create a secondary stream key for each one.
What happens if I reset my stream key by accident?
Your old key stops working immediately, and your broadcast will disconnect if you are currently streaming. You will need to update your broadcasting software with the new key before you can go live again. If you reset it by accident, you can reset it again to get a different key, but there is no way to get the old one back.
Do I need to change my stream key regularly for security?
No, you do not need to change it on a schedule. Only reset your stream key if you think it has been exposed or if you want to revoke access for someone. Changing it frequently does not make your channel more secure — keeping it private does.
Can someone stream to my channel if they only know my username?
No. They need your actual stream key, not just your channel name. Your username is public, but your stream key is private. Knowing your username alone does not let anyone broadcast to your channel.
Where do I find my stream key on mobile?
The Twitch mobile app does not let you view or manage your stream key. You need to use a web browser on a computer or tablet. Log into Twitch.tv, go to Creator Dashboard, Settings, and Stream to find your key there.
