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:

- Create and configure a Twitch Application [Twitch Developer Console](https://dev.twitch.tv/console)
- Add your Twitch OAuth Consumer keys to your [Supabase Project](/dashboard)
- Add the login code to your [Supabase JS Client App](https://github.com/supabase/supabase-js)

## Access your Twitch Developer account

- Go to [dev.twitch.tv](https://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](https://www.twitch.tv/settings/security) before you can continue.

- Once logged in, go to the [Twitch Developer Console](https://dev.twitch.tv/console).

```js
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('<your-project-url>', '<sb_publishable_... or anon key>')

When your user signs in, call [`signInWithOAuth()`](/docs/reference/dart/auth-signinwithoauth) with `twitch` as the `provider`:

    OAuthProvider.twitch,
    redirectTo: kIsWeb ? null : 'my.scheme://my-host', // Optionally set the redirect link to bring back the user via deeplink.
    authScreenLaunchMode:
        kIsWeb ? LaunchMode.platformDefault : LaunchMode.externalApplication, // Launch the auth screen in a new webview on mobile.
