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](https://supabase.com)
- Add the login code to your [Supabase JS Client App](https://github.com/supabase/supabase-js)
## Steps
### 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).

### Find your callback URL
In the next step you require a callback URL, which looks like this:
`https://<project-ref>.supabase.co/auth/v1/callback`
- Go to your [Supabase Project Dashboard](https://supabase.com).
- 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](/docs/img/guides/twitch-console.png)
- Click on `+ Register Your Application` at the top right.
![Register Application](/docs/img/guides/twitch-register-your-application.png)
- 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](/docs/img/guides/twitch-applications-list.png)
- Copy your Client ID.
- Click `New Secret` to create a new Client Secret.
- Copy your Client Secret.

### Add your Twitch credentials into your Supabase Project
- Go to your [Supabase Project Dashboard](https://supabase.com)
- 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](/docs/reference/javascript/auth-signin#sign-in-using-third-party-providers)
```js
const { user, session, error } = await supabase.auth.signIn({
provider: 'twitch',
})
```
Add this function which you can call from a button, link, or UI element.
```js
async function signInWithTwitch() {
const { user, session, error } = await supabase.auth.signIn({
provider: 'twitch',
})
}
```
To log out:
```js
async function signout() {
const { error } = await supabase.auth.signOut()
}
```
