### Assumptions

This example makes the following assumptions:

- __Application Root URL:__ `https://wanderer.{{< sitevar name="domain" nojs="example.com" >}}/`
  - Wanderer uses the `ORIGIN` environment variable as the public URL. The redirect URL is `${ORIGIN}/login/redirect`.
- __Authelia Root URL:__ `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/`
- __Client ID:__ `wanderer`
- __Client Secret:__ `insecure_secret`

Some of the values presented in this guide can automatically be replaced with documentation variables.

## Configuration

### Authelia

The following YAML configuration is an example __Authelia__ [client configuration] for use with [Wanderer] which will
operate with the application example:

```yaml {title="configuration.yml"}
identity_providers:
  oidc:
    ## The other portions of the mandatory OpenID Connect 1.0 configuration go here.
    ## See: https://www.authelia.com/c/oidc
    clients:
      - client_id: 'wanderer'
        client_name: 'Wanderer'
        client_secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
        public: false
        authorization_policy: 'two_factor'
        require_pkce: true
        pkce_challenge_method: 'S256'
        redirect_uris:
          - 'https://wanderer.{{< sitevar name="domain" nojs="example.com" >}}/login/redirect'
        scopes:
          - 'openid'
          - 'email'
          - 'profile'
        response_types:
          - 'code'
        grant_types:
          - 'authorization_code'
        access_token_signed_response_alg: 'none'
        userinfo_signed_response_alg: 'none'
        token_endpoint_auth_method: 'client_secret_basic'
```

### Application

Wanderer uses PocketBase for authentication configuration. To configure [Wanderer] to utilize Authelia as an
[OpenID Connect 1.0] Provider:

1. Sign in to the PocketBase admin UI using your superuser.
2. Navigate to the `users` collection.
3. Click the gear icon to open the collection settings.
4. Navigate to `Options`.
5. In the `OAuth2` tab, add a new provider with type `OpenID Connect (oidc)`.
6. Configure the provider with these options:

    - Client ID: `wanderer`
    - Client secret: `insecure_secret`
    - Display name: `Authelia`
    - Auth URL: `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/api/oidc/authorization`
    - Token URL: `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/api/oidc/token`
    - Fetch user info from: `User info URL`
    - User info URL: `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/api/oidc/userinfo`
    - Support PKCE: enabled

1. Save your changes.

Ensure the redirect URL configured at the provider is exactly `${ORIGIN}/login/redirect` and that the same value is
present in the Authelia `redirect_uris` list.
