User management

[Q-it]

I've recently developed a website that integrates with the Spotify API, allowing users to authenticate with their Spotify accounts and search for songs. I'm now ready to share the site with others, but I'm running into an issue with user management. Since I can't manually add every user's email to the Spotify developer dashboard, I'm wondering if there's an alternative way to allow broader access.

As an individual developer without a legally registered business, I'm also concerned about Spotify's recent changes regarding quota extensions, which seem to restrict them to registered entities. Is there any workaround or process available for independent developers to request extended access?
