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.
FirebaseUI provides a customizable, open source, drop-in auth solution that handles the UI flows for signing in users. The FirebaseUI Auth component implements best practices for authentication on mobile devices and websites, which can maximize sign-in and sign-up conversion for your app.
Comprehensive security
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.
Fast implementation
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.
Case Studies
Learn how Authentication helps teams across the world improve app quality
STAGE uses Firebase and Flutter to cut release time in half
STAGE paired Flutter's front-end tools with Firebase's back-end services to build a multi-platform app. The app's infrastructure securely stores and delivers content to almost 2 million users in real time for a smooth viewing experience, which helps them stand out in India's competitive streaming market.
Acintyo uses Firebase to streamline and speed up app development by 25%
With millions of users across 175 countries, the Galarm team used Firebase's fully-managed, scalable infrastructure to accelerate app development, automate tasks, and free up engineering time so they could focus on bringing their ideas to life.
