# Last.fm

<a id="backend-class"></a>

## 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                               |
|----------------|------------------------------------------|
| `lastfm`       | `social_core.backends.lastfm.LastFmAuth` |

Last.fm uses a similar authentication process than OAuth2 but it’s not. In
order to enable the support for it just:

- Register an application at [Get an API Account](http://www.last.fm/api/account/create), set the Last.fm callback to
  something sensible like [http://your.site/complete/lastfm](http://your.site/complete/lastfm)
- Fill in the **API Key** and **API Secret** values in your settings:
  ```default
  SOCIAL_AUTH_LASTFM_KEY = ''
  SOCIAL_AUTH_LASTFM_SECRET = ''
  ```
- Enable the backend in `AUTHENTICATION_BACKENDS` setting.

Last.fm does not expose a stable account identifier in its authentication
session response. The backend is therefore association-only: an authenticated
local user must initiate and complete the connection. Last.fm cannot create a
local user or authenticate a logged-out user.
