## Tested Versions

* [Authelia]
  * [v4.36.3](https://github.com/authelia/authelia/releases/tag/v4.36.3)
* [Gitea]
  * [1.17.0](https://github.com/go-gitea/gitea/releases/tag/v1.17.0)

## Before You Begin

### Common Notes

1. You are *__required__* to utilize a unique client id for every client.
2. The client id on this page is merely an example and you can theoretically use any alphanumeric string.
3. You *__should not__* use the client secret in this example, We *__strongly recommend__* reading the
   [Generating Client Secrets] guide instead.

### Assumptions

This example makes the following assumptions:

* __Application Root URL:__ `https://gitea.example.com`
* __Authelia Root URL:__ `https://auth.example.com`
* __Client ID:__ `gitea`
* __Client Secret:__ `gitea_client_secret`

## Configuration

### Application

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

1. Expand User Options
2. Visit Site Administration
3. Visit Authentication Sources
4. Visit Add Authentication Source
5. Configure:
   1. Authentication Name: `authelia`
   2. OAuth2 Provider: `OpenID Connect`
   3. Client ID (Key): `gitea`
   4. Client Secret: `gitea_client_secret`
   5. OpenID Connect Auto Discovery URL: `https://auth.example.com/.well-known/openid-configuration`

{{< figure src="gitea.png" alt="Gitea" width="300" >}}

To configure [Gitea] to perform automatic user creation for the `auth.example.com` domain via [OpenID Connect]:

1. Edit the following values in the [Gitea] `app.ini`:
```ini
[openid]
ENABLE_OPENID_SIGNIN = false
ENABLE_OPENID_SIGNUP = true
WHITELISTED_URIS     = auth.example.com

[service]
DISABLE_REGISTRATION                          = false
ALLOW_ONLY_EXTERNAL_REGISTRATION              = true
SHOW_REGISTRATION_BUTTON                      = false
```

Take a look at the [See Also](#see-also) section for the cheatsheets corresponding to the sections above for their
descriptions.

### Authelia

The following YAML configuration is an example __Authelia__
[client configuration](../../../configuration/identity-providers/open-id-connect.md#clients) for use with [Gitea] which
will operate with the above example:

```yaml
- id: gitea
  description: Gitea
  secret: '$plaintext$gitea_client_secret'
  public: false
  authorization_policy: two_factor
  redirect_uris:
    - https://gitea.example.com/user/oauth2/authelia/callback
  scopes:
    - openid
    - email
    - profile
  userinfo_signing_algorithm: none
```
