1. Choose "My Apps" > "Add a New App"

1. Select the type "Website"

1. Enter a name for your app. This can be anything. Consider something like
   "<Organization>'s GitLab" or "<Your Name>'s GitLab" or something
   else descriptive.

1. Choose "Create New Facebook App ID"

1. Select a Category, for example "Productivity"

1. Choose "Create App ID"

1. Enter the address of your GitLab installation at the bottom of the package

   open as you continue configuration.

1. On your GitLab server, open the configuration file.

   For Omnibus package:

   ```shell
   sudo editor /etc/gitlab/gitlab.rb
   ```

   For installations from source:

   ```shell
   cd /home/git/gitlab

   sudo -u git -H editor config/gitlab.yml
   ```

1. Edit the [common configuration file settings](omniauth.md#configure-common-settings)
   to add `facebook` as a single sign-on provider. This enables Just-In-Time
   account provisioning for users who do not have an existing GitLab account.

1. Add the provider configuration:

   For Omnibus package:

   ```ruby
   gitlab_rails['omniauth_providers'] = [
     {
       name: "facebook",
       # label: "Provider name", # optional label for login button, defaults to "Facebook"
       app_id: "YOUR_APP_ID",
       app_secret: "YOUR_APP_SECRET"
     }
   ]
   ```

   For installations from source:

   ```yaml
   - { name: 'facebook',
       # label: 'Provider name', # optional label for login button, defaults to "Facebook"
       app_id: 'YOUR_APP_ID',
       app_secret: 'YOUR_APP_SECRET' }
   ```

1. Change 'YOUR_APP_ID' to the API key from Facebook page in step 10.

1. Change 'YOUR_APP_SECRET' to the API secret from the Facebook page in step 10.

1. Save the configuration file.

1. For the changes to take effect:
   - If you installed via Omnibus, [reconfigure GitLab](../administration/restart_gitlab.md#omnibus-gitlab-reconfigure).
   - If you installed from source, [restart GitLab](../administration/restart_gitlab.md#installations-from-source).

On the sign in page there should now be a Facebook icon below the regular sign
in form. Select the icon to begin the authentication process. Facebook asks the
user to sign in and authorize the GitLab application. If everything goes well
the user is returned to GitLab and signed in.
