:::caution
You might run into CSRF errors, this is caused by a technology Home-assistant uses and not authentik, see [this GitHub issue](https://github.com/goauthentik/authentik/issues/884#issuecomment-851542477).
:::
:::note
For Home Assistant to work with authentik, a custom integration needs to be installed for Home Assistant.
:::
## Preparation
The following placeholders will be used:
- `hass.company` is the FQDN of the Home-Assistant install.
- `hass.company` is the FQDN of the Home Assistant install.
- `authentik.company` is the FQDN of the authentik install.
## Home-Assistant
## Home Assistant configuration
This guide requires https://github.com/BeryJu/hass-auth-header, which can be installed as described in the Readme.
1. Configure [trusted_proxies](https://www.home-assistant.io/integrations/http/#trusted_proxies) for the HTTP integration with the IP(s) of the Host(s) authentik is running on.
2. If you don't already have it set up, install https://github.com/BeryJu/hass-auth-header, using the installation guide.
3. There are two ways to configure the custom component.
Afterwards, make sure the `trusted_proxies` setting contains the IP(s) of the Host(s) authentik is running on.
1. To match on the user's authentik username, use the following configuration:
Use this configuration to match on the user's authentik username.
```yaml
auth_header:
username_header: X-authentik-username
```
```yaml
auth_header:
username_header: X-authentik-username
```
2. Alternatively, you can associate an existing Home Assistant username to an authentik username.
1. Within authentik, naviagte to **Directory** > **Users**.
2. Select **Edit** for the user then add the following configuration to the **Attributes** section. Be sure to replace `hassusername` with the Home Assistant username.
If this is not the case, you can simply add an additional header for your user, which contains the Home-Assistant Name and authenticate based on that.
:::note
This configuration will add an additional header for the authentik user which will contain the Home Assistant username and allow Home Assistant to authenticate based on that.
:::
For example add this to your user's properties and set the Header to `X-ak-hass-user`.
```yaml
additionalHeaders:
X-ak-hass-user: hassusername
```
```yaml
additionalHeaders:
X-ak-hass-user: some other name
```
3. Then configure the Home Assistant custom component to use this header:
```yaml
auth_header:
username_header: X-ak-hass-user
```
## authentik
## authentik configuration
Create a Proxy Provider with the following values
1. Create a **Proxy Provider** under **Applications** > **Providers** using the following settings:
- Internal host
- **Name**: Home Assistant
- **Authentication flow**: default-authentication-flow
- **Authorization flow**: default-provider-authorization-explicit-consent
- **External Host**: Set this to the external URL you will be accessing Home Assistant from
- **Internal Host**: `http://hass.company:8123`
If Home-Assistant is running in docker, and you're deploying the authentik proxy on the same host, set the value to `http://homeassistant:8123`, where Home-Assistant is the name of your container.
2. Create an **Application** under **Applications** > **Applications** using the following settings:
- **Name**: Home Assistant
- **Slug**: homeassistant
- **Provider**: Home Assistant (the provider you created in step 1)
If Home-Assistant is running on a different server than where you are deploying the authentik proxy, set the value to `http://hass.company:8123`.
- External host
Set this to the external URL you will be accessing Home-Assistant from.
Create an application in authentik and select the provider you've created above.
## Deployment
Create an outpost deployment for the provider you've created above, as described [here](../../../docs/outposts/). Deploy this Outpost either on the same host or a different host that can access Home-Assistant.
The outpost will connect to authentik and configure itself.
