Spotify Password Authentication Deprecated

[goshansp]

Password authentication for Spotify has been deprecated and it's not working anymore with:

[Error] (librespot) could not initialize spirc: Permission denied { Login failed with reason: Bad credentials }

It seems that Snapcast needs to switch to token-based authentication and hence we'll require this container to handle the API token variable and documentation requires update.

The workaround is moving to Zeroconf as mentioned here :

• remove SPOTIFY_USERNAME and 'SPOTIFY_PASSWORD from container runtime (as shown in command below)
• remove SPOTIFY_USERNAME and 'SPOTIFY_PASSWORD from snapserver.conf
• move container to host network i.e. for podman run add --network=host

Full command that is working for me
$ podman run -p '1704-1705:1704-1705' -p '1780:1780' -p '3689:3689' -p '6000-6009:6000-6009/udp' -p '5353:5353' -p '443:443' -e 'SPOTIFY_CONFIG_ENABLED=1' -v 'snapcast-config:/app/config/' --name snapcast --rm --network=host ghcr.io/firefrei/snapcast/server:latest

PR #10 already changed SPOTIFY_USERNAME and SPOTIFY_PASSWORD to optional variables. So you can just leave them empty/unconfigured, and librespot will operate in zeroconf mode by default. Therefore, your Spotify app client needs to be in the same L2 subnet - as you mentioned by --network=host.
However, the fix was not yet included in the latest image tag, only in the dev. I have pushed a new latest version now.

Great work, thank you so much! I was not aware of Zeroconf before the deprecation and it fits my use case much better. The family loves it! I cannot think of a reason to switch back to username and password. Please re-open if you disagree.
