## Configuration
**GoDeez** requires a Deezer ARL cookie for authentication. Set it as an environment variable:
**GoDeez** authenticates to Deezer in one of two ways: with an **ARL cookie** copied from your browser, or with your **email and password**. The ARL cookie works out of the box and is the recommended option; email/password login requires two extra keys that **GoDeez** does not ship (see below).
### ARL cookie
Set your ARL cookie as an environment variable:
```bash
export DEEZER_ARL="your_arl_cookie_here"
@@ -98,29 +99,60 @@ export DEEZER_ARL="your_arl_cookie_here"
To make it persistent, add the line above to your shell profile (`~/.bashrc`, `~/.zshrc`, etc.).
### How to retrieve your ARL cookie
#### How to retrieve your ARL cookie
1. Open your browser and log in to your [Deezer](https://www.deezer.com) account.
2. Open the Developer Tools (right-click on the page and select “Inspect” or press F12).
2. Open the **Developer Tools** (right-click on the page and select **Inspect**, or press <kbd>F12</kbd>).
3. Navigate to the **Application** tab (Chrome/Edge) or **Storage** tab (Firefox).
4. In the left panel, look for **Cookies** and select `https://www.deezer.com`.
4. In the left panel, look for **Cookies** and select **https://www.deezer.com**.
5. Find the `arl` cookie and copy its value.
> **Note:** The ARL cookie may expire after some time. If you get authentication errors, retrieve a fresh cookie using the steps above.
### Email and password
Instead of copying a cookie, you can log in once with your Deezer account:
```bash
godeez login
```
You will be prompted for your email and password. On success, **GoDeez** stores your credentials in your system keyring under the service name `godeez`. From then on, **GoDeez** authenticates on its own and renews the session when it expires.
To remove the stored credentials:
```bash
godeez logout
```
#### Gateway keys
Email/password login goes through Deezer's mobile gateway, which requires two keys:
```bash
export DEEZER_MOBILE_API_KEY="your_api_key_here"
export DEEZER_MOBILE_GW_KEY="your_gateway_key" # exactly 16 characters
```
**GoDeez** does not bundle these keys, so you have to supply your own. For background on what they are and where they live in Deezer's clients, see [this write-up](https://gist.github.com/svbnet/b79b705a4c19d74896670c1ac7ad627e). If either variable is missing, `godeez login` exits with an error.
> **Note:** `DEEZER_ARL` takes precedence over stored credentials. If it is set, **GoDeez** always uses the cookie and never falls back to your login, so unset it (and remove it from your shell profile) before running `godeez login`.
> **Note:** The keyring entry holds your password alongside the ARL because the password is reused to renew expired sessions. On Linux, the keyring requires a running secret service; without one, `godeez login` fails with `system keyring is unavailable`.
### Output directory
Downloaded files are saved to `~/Music/GoDeez`. The download database (`.tracks.db`) is stored alongside your music in the output directory.
Downloaded files are saved to `~/Music/GoDeez`. The download database (`.tracks.db`) is stored in the same directory as your music.
> **Upgrading from v1.3.0?** The `~/.godeez` directory and `config.toml` are no longer used. Set the `DEEZER_ARL` environment variable instead. Your existing database will be migrated automatically on first run.
