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

## Overview

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

- Create and configure a GitLab Application on [GitLab](https://gitlab.com)
- Add your GitLab Application keys to your [Supabase Project](/dashboard)
- Add the login code to your [Supabase JS Client App](https://github.com/supabase/supabase-js)

## Access your GitLab account

- Go to [gitlab.com](https://gitlab.com).
- Click on `Login` at the top right to log in.

## Find your callback URL

## Create your GitLab application

- Click on your `profile logo` (avatar) in the top-right corner.
- Select `Edit profile`.
- In the left sidebar, select Applications.
- Enter the name of the application.
- In the `Redirect URI` box, type the callback URL of your app.
- Check the box next to `Confidential` (make sure it is checked).
- Check the scope named `read_user` (this is the only required scope).
- Click `Save Application` at the bottom.
- Copy and save your `Application ID` (`client_id`) and `Secret` (`client_secret`) which you'll need later.

import { createClient } from '@supabase/supabase-js'
const supabase = createClient(
  'https://your-project-id.supabase.co',
  'sb_publishable_... or anon key'

    provider: 'gitlab',
  })
}
```

    OAuthProvider.gitlab,
    redirectTo: kIsWeb ? null : 'my.scheme://my-host', // Optionally set the redirect link to bring back the user via deeplink.
