Authentication
Federated identity provider integration
Authenticate users by integrating with federated identity providers. The Firebase Authentication SDK provides methods that allow users to sign in with their Google, Facebook, Twitter, and GitHub accounts.
(통합 로그인을 지원해주는 연합과 통합하여 사용자를 인증합니다. Firebase Authentication SDK는 구글, 페이스북, 트위터 그리고 깃허브 계정을 통한 로그인을 지원합니다.)
