Login with Twitch

To enable Twitch Auth for your project, you need to set up a Twitch Application and add the Application OAuth credentials to your Supabase Dashboard.


Setting up Twitch logins for your application consists of 3 parts:


Access your Twitch Developer account

  • Go to
  • Click on Log in with Twitch at the top right to log in.
  • If you have not already enabled 2-Factor Authentication for your Twitch Account, you will need to do that at Twitch Security Settings before you can continue.

Twitch Developer Page

Twitch Developer Console

Find your callback URL

In the next step you require a callback URL, which looks like this:


  • Go to your Supabase Project Dashboard.
  • Click on the Settings icon at the bottom of the left sidebar.
  • Click on API in the list.
  • Under Config / URL you'll find your API URL, you can click Copy to copy it to the clipboard.
  • Now just add /auth/v1/callback to the end of that to get your full OAuth Redirect URI.

Create a Twitch Application

Twitch Developer Console

  • Click on + Register Your Application at the top right.

Register Application

  • Enter the name of your application.
  • Type or paste your OAuth Redirect URL (the callback URL from the previous step.)
  • Select a category for your app.
  • Check the Captcha box and click Create.

Retrieve your Twitch OAuth Client ID and Client Secret

  • Click Manage at the right of your application entry in the list.

Twitch Applications List

  • Copy your Client ID.
  • Click New Secret to create a new Client Secret.
  • Copy your Client Secret.

Get Client ID and Secret

Add your Twitch credentials into your Supabase Project

  • Go to your Supabase Project Dashboard
  • In the left sidebar, click the Authentication icon (near the top)
  • Click Settings from the list to go to the Authentication Settings page
  • Enter the final (hosted) URL of your app under Site URL (this is important)
  • Under External OAuth Providers turn Twitch Enabled to ON
  • Enter your client_id and client_secret saved in the previous step
  • Click Save

Add login code to your client app

The JavaScript client code is documented here: Supabase OAuth Client Code

const { user, session, error } = await supabase.auth.signIn({
provider: 'twitch',

Add this function which you can call from a button, link, or UI element.

async function signInWithTwitch() {
const { user, session, error } = await supabase.auth.signIn({
provider: 'twitch',

To log out:

async function signout() {
const { error } = await supabase.auth.signOut()
