## Configuration

### Authelia

The following YAML configuration is an example __Authelia__ [client configuration] for use with [Komga] 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: 'komga'
        client_name: 'Komga'
        client_secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
        public: false
        authorization_policy: 'two_factor'
        redirect_uris:
          - 'https://komga.{{< sitevar name="domain" nojs="example.com" >}}/login/oauth2/code/authelia'
        scopes:
          - 'openid'
          - 'profile'
          - 'email'
        grant_types:
          - 'authorization_code'
        userinfo_signed_response_alg: 'none'
```

### Application

To configure [Komga] to utilize Authelia as an [OpenID Connect 1.0] Provider:

1. Configure the security section of the [Komga] configuration:
```yaml
komga:
  ## Comment if you don't want automatic account creation.
  oauth2-account-creation: true
spring:
  security:
    oauth2:
      client:
        registration:
          authelia:
            client-id: 'komga'
            client-secret: 'insecure_secret'
            client-name: 'Authelia'
            scope: 'openid,profile,email'
            authorization-grant-type: 'authorization_code'
            redirect-uri: "{baseScheme}://{baseHost}{basePort}{basePath}/login/oauth2/code/authelia"
        provider:
          authelia:
            issuer-uri: 'https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}'
