Integrates robust OAuth2 social authentication across GitHub, Google, Facebook, and Twitter for Stacks apps, handling provider flows, PKCE when needed, and consistent user mapping.
Configure an OAuth2 login flow by instantiating a provider, calling getAuthUrl to start the flow, then exchange the code with getAccessToken and finally retrieve the user with getUserByToken.

Add OAuth2 social login by instantiating a provider, calling getAuthUrl to start the flow, exchanging the code with getAccessToken, and retrieving the user with getUserByToken. This handles GitHub, Google, Facebook, and Twitter authentication.
Handle GitHub, Google, Facebook, and Twitter authentication using an AbstractProvider base class with per-provider drivers. It normalizes user profiles into a unified SocialUser shape while managing tokens and provider-specific flows.
Yes, Stacks social login supports PKCE for Twitter along with standard state management. The implementation reads credentials from config.services and handles scope management across all supported providers.
Yes, you can use social sign-in for both web and server Stacks applications. The implementation applies to any Stacks app needing OAuth2 social authentication, user profile normalization, and token handling.
User profiles are normalized across different OAuth2 providers by fetching raw provider data and mapping it to a unified SocialUser shape. The returned SocialUser object includes the original raw provider data alongside the normalized fields.
Configure OAuth2 credentials and default scopes in the config.services file. The provider drivers read these credentials and scope settings directly from this configuration to generate authorization URLs and exchange tokens.
