## Backend class

For Django, add this class path to `AUTHENTICATION_BACKENDS`. For other
integrations, use the same class path in the framework-specific backend
setting.

| Backend name   | Class path                                       |
|----------------|--------------------------------------------------|
| `launchpad`    | `social_core.backends.launchpad.LaunchpadOpenId` |

[Ubuntu Launchpad](https://launchpad.net/) OpenID doesn’t require
major settings beside being defined on `AUTHENTICATION_BACKENDS``:

```default
SOCIAL_AUTH_AUTHENTICATION_BACKENDS = (
    ...
    'social_core.backends.launchpad.LaunchpadOpenId',
    ...
)
```
