Firebase Authentication
Simple, multi-platform sign-in
Provides backend services, easy-to-use SDKs, and ready-made UI libraries to authenticate users to your app.
Acceso sencillo con cualquier plataforma
Firebase Authentication aims to make building secure authentication systems easy, while improving the sign-in and onboarding experience for app users. It provides an end-to-end identity solution, supporting email and password accounts, phone auth, Google, Apple, X, Facebook, GitHub login, and more.

IU flexible y directa
FirebaseUI proporciona una solución de autenticación directa, personalizable y de código abierto que administra los flujos de IU para el acceso de los usuarios. El componente de FirebaseUI Auth implementa recomendaciones para la autenticación en sitios web y dispositivos móviles, lo que puede maximizar la conversión de acceso y registro de tu app.
Seguridad integral
Built by the same team that developed Google Sign-in, Smart Lock and Chrome Password Manager, Authentication securely applies Google's internal expertise of managing one of the largest account databases in the world.


Implementación rápida
It can take months to set up your own authentication system, and it requires an engineering team to maintain that system in the future. You can set up the entire authentication system of your app, capable of handling even complex cases like account merging, in under 10 lines of code.
