Firebase Authentication Mobile
Firebase Authentication handles user login, signup, password resets, and multi-factor authentication (MFA). Supports email/password, phone (SMS OTP), Google/Facebook OAuth, Apple Sign-In, and passwordless. Integrate in 1 hour (add SDK, call Firebase APIs). Learning: 1-2 weeks for basic auth, 4-6 weeks for complex flows (social login, custom claims, session management). Practitioners building secure auth flows earn 10% premium because security is hard to ship right. Firebase Auth removes 80% of auth implementation burden.
What is Firebase Authentication Mobile
Firebase Authentication is Google's identity platform for apps. It handles user login, signup, password resets, email verification, phone verification (SMS), and multi-factor authentication. Integrate the SDK (1 line: pod 'Firebase/Auth'), call authentication APIs, and get a user session. Firebase secures passwords, manages tokens, and handles account recovery. It supports multiple auth methods: email/password, phone (SMS OTP), Google, Facebook, Apple, Twitter, Microsoft, GitHub, and anonymous. Users can link multiple methods to one account.
