Yep, spotDL is nice. It does however not download from Spotify directly because of legal reasons. Instead, it searches the songs on other sites, for example YouTube Music, and downloads them from there. So YMMV based on which songs you’re trying to get.

Ohhhh, this looks promising!

Same here.

Bitwarden doesnt rely on the cloud either. You can host it yourself or use another backend like Vaultwarden.
