Is it possible to register in social networks through the gigya.com service without a browser?

Question

Android

Hello.
I read the documentation, look at gigya.com examples, I get the impression that all registration and authorization is only using a browser, the customer sees this service as a kind of silver bullet, I agree that it will solve some of the problems on the server ... maybe in the future ...
Am I correct I understand that everything they write is stupid marketing and normally they don’t use api services on the client and connect stupidly through the browser?
