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

## Steps

### 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

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](https://app.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 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.

### Add your GitLab credentials into your Supabase Project

- Go to your [Supabase Project Dashboard](https://app.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 `GitLab 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: 'gitlab',
})
```

Add this function which you can call from a button, link, or UI element.

```js
async function signInWithGitLab() {
  const { user, session, error } = await supabase.auth.signIn({
    provider: 'gitlab',
  })
}
```

To log out:

```js
async function signout() {
  const { error } = await supabase.auth.signOut()
}
```
