I will add firebase email, google, or phone otp login to your flutter app
Mobile App Developer, iOS and Android
About this Gig
Need secure login for your Flutter app? I'll integrate Firebase Authentication with email/password, Google Sign-In, or phone OTP verification the same authentication system I built for a live production app with student, driver, and admin roles.
What I handle:
- Email/password login with validation
- Google Sign-In integration
- Phone number OTP verification
- Password reset flow
- Role-based access for apps with multiple user types
I don't just flip a Firebase toggle I handle real edge cases: expired OTPs, wrong codes, session persistence, and clear error messages so your users never get stuck.
Send me your current setup and which login method(s) you need, and I'll tell you exactly how I'd build it into your app

FAQ
Do you need my codebase?
Yes — I integrate directly into your existing Flutter project so everything stays consistent.
Do I need my own Firebase project already set up?
No, if you don't have one I'll help set it up — it's free on Firebase's Spark plan.
Can you add role-based login (admin vs regular user)?
Yes, included in the Premium package.
