## Configuring Authelia Authentication Service

## Authelia Configuration Flow

<Steps>
  ### Create an Authelia Identity Provider

  We assume you are already familiar with using Authelia. Let's say your LobeChat instance is deployed at [https://lobe.example.com/](https://lobe.example.com/). Note that currently only localhost supports HTTP access; other domains need to enable TLS, otherwise Authelia will actively interrupt authentication by default.

  Now, let's open and edit the configuration file of your Authelia instance:

  Add a new lobe-chat item under `identity_providers` -> `oidc`:

  ```yaml
  identity_providers:
    oidc:
      ...
      ## The other portions of the mandatory OpenID Connect 1.0 configuration go here.
      ## See: https://www.authelia.com/c/oidc
      - id: lobe-chat
        description: LobeChat
        secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
        public: false
        authorization_policy: two_factor
        redirect_uris:
          - https://chat.example.com/api/auth/callback/authelia
        scopes:
          - openid
          - profile
          - email
        userinfo_signing_algorithm: none
  ```

  Make sure to replace secret and `redirect_urls` with your own values. Note! The secret configured in Authelia is ciphertext, i.e., a salted hash value. Its corresponding plaintext needs to be filled in LobeChat later.

  Save the configuration file and restart the Authelia service. Now we have completed the Authelia configuration.

  ### Configure Environment Variables

  When deploying LobeChat, you need to configure the following environment variables:

  | Environment Variable      | Type     | Description                                                                                                                                                                                                                                               |
  | ------------------------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
  | `NEXT_AUTH_SECRET`        | Required | The secret used to encrypt Auth.js session tokens. You can generate a secret using the following command: `openssl rand -base64 32`                                                                                                                       |
  | `NEXT_AUTH_SSO_PROVIDERS` | Required | Select the SSO provider for LoboChat. Use `authentik` for Authentik.                                                                                                                                                                                      |
  | `AUTH_AUTHELIA_ID`        | Required | The id just configured in Authelia, example value is lobe-chat                                                                                                                                                                                            |
  | `AUTH_AUTHELIA_SECRET`    | Required | The plaintext corresponding to the secret just configured in Authelia, example value is `insecure_secret`                                                                                                                                                 |
  | `AUTH_AUTHELIA_ISSUER`    | Required | Your Authelia URL, for example [https://sso.example.com](https://sso.example.com)                                                                                                                                                                         |
  | `NEXTAUTH_URL`            | Required | This URL is used to specify the callback address for Auth.js when performing OAuth verification. It only needs to be set when the default generated redirect address is incorrect. [https://chat.example.com/api/auth](https://chat.example.com/api/auth) |
