Login Broker is social login you finish in five minutes: one script tag, one API key, six providers (Google, Facebook, Microsoft, Apple, GitHub, LinkedIn). You never register apps with those providers, never store client secrets, and never validate ID tokens. The callback lands on our domain so localhost and production work the same. You get a verified email and go back to building. Free forever up to 100,000 monthly active users, no card.
I got tired of standing up six developer consoles just to put Sign in with Google, GitHub and Apple on a side project. The OAuth spec is real, it is long, and none of it is the product I was actually trying to ship. Login Broker is the button that works before lunch.
