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.

Overview

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

Access your Twitch Developer account

  • Go to dev.twitch.tv.
  • 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.

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

  • Go to your Supabase Project Dashboard
  • Click on the Authentication icon in the left sidebar
  • Click on Providers under the Configuration section
  • Click on Twitch from the accordion list to expand and you'll find your Redirect URL, you can click Copy to copy it to the clipboard

  • Click on Twitch from the accordion list to expand and turn Twitch Enabled to ON

Add login code to your client app

When your user signs in, call signInWithOAuth() with twitch as the provider:


_10
async function signInWithTwitch() {
_10
const { data, error } = await supabase.auth.signInWithOAuth({
_10
provider: 'twitch',
_10
})
_10
}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:


_10
async function signOut() {
_10
const { error } = await supabase.auth.signOut()
_10
}
