Non-dev user authentication possible?

[MattMills]

I see from the code here that this API/session ticket code requires a secret key, which I'm assuming is something only game developers have access to.

I'm currently building a web based tool (in PHP) that will be used to troubleshoot mod interaction within the game Stellaris, but I'm not the game developer. Does this API include (and if not, could you consider this a feature request for) any user-initiated SSO authentication not requiring any secrets, for example, I'm using this API for Steam auth: https://partner.steamgames.com/doc/features/auth#website which allows the user to click a button, then get sent to steam for login and approval of sharing their Steam ID, which gets sent back to me in such a way I can independently verify it against a steam server.

Thanks,
Matt.

@goggalaxy Is there any solution for this? I'm developing web based tooling for one of your games and I'd like to be able to allow gog users to login without telling them to get a steam account...
