You can now add "Sign in with X" to your application using the new **X / Twitter (OAuth 2.0)** provider in Supabase Auth.

## What's new

The new provider uses X's OAuth 2.0 implementation, replacing the legacy OAuth 1.0a flow. OAuth 2.0 offers a more modern authentication experience with better security practices, including PKCE support.

## Getting started

Setting up X / Twitter authentication takes a few steps:

1. Create an OAuth 2.0 app in the [X Developer Portal](https://developer.x.com/en/portal/dashboard)
1. Enable "Request email from users" in your app's authentication settings
1. Add your callback URL from the Supabase dashboard
1. Copy your **Client ID** and **Client Secret** from the "Keys and tokens" section
1. Enter these credentials in **Authentication > Providers > X / Twitter (OAuth 2.0)** in the Supabase dashboard

Once configured, you can use the Supabase client libraries to authenticate users via X / Twitter:

```javascript
const { data, error } = await supabase.auth.signInWithOAuth({
  provider: 'x',
})
```

For a complete guide on setting up X / Twitter authentication, see the [full documentation](/docs/guides/auth/social-login/auth-twitter).

## Migration note

If you're currently using the legacy **Twitter (OAuth 1.0a)** provider, we recommend migrating to the new OAuth 2.0 provider. The legacy provider will remain available while X / Twitter continues to support OAuth 1.0a.
