I will integrate firebase oauth jwt authentication into your reactjs or nextjs app
Measum Naqi
About this gig
Your app is only as safe as its login system. Let's build it right.
I'm Measum, a backend developer specializing in authentication and authorization for Node.js, React, and Firebase applications. If you need secure, production-ready login not a tutorial copy-paste you're in the right place.
What I set up for you:
- Login and signup with full input validation and error handling
- JWT authentication with refresh token rotation and secure storage
- Firebase Auth, OAuth (Google, GitHub), or Clerk integration
- Role-based access control admin, user, moderator, or custom roles
- Protected routes on both frontend and backend
- Password hashing (bcrypt), rate limiting, and brute-force protection
- Session management and secure logout
Why this matters:
Weak authentication is the #1 entry point for data breaches. I don't just make login work I make it secure. Every system I deliver follows OWASP security standards, uses environment-based config (no hardcoded secrets), and is written in clean, modular code you can actually maintain.
You'll receive:
- Fully working auth system integrated into your existing codebase
- Clear documentation of every route, token flow, and role rule
- Clean commit history so you under

FAQ
Will this authentication system be secure enough for real-world use?
Yes. I follow best practices such as password hashing with bcrypt, secure JWT token handling, route protection, and input validation. The code you receive is clean, reliable, and ready for production environments.
Can you integrate this with my existing web app?
Absolutely. I can work with your current tech stack (Node.js, Express, MongoDB, etc.) and integrate the authentication system smoothly without breaking existing features. Just share the repo or code access after ordering.
What roles can you set up in the role-based system?
You can define any roles you need, such as admin, user, editor, etc. I’ll implement access control based on your requirements, so each role only sees and performs actions allowed by your system’s logic.
Which authentication methods do you support?
I support JWT (with refresh token rotation), Firebase Authentication, OAuth 2.0 (Google, GitHub, Facebook), Clerk, and session-based auth. If you're using a specific stack or provider not listed here, message me — chances are I've worked with it or can integrate it cleanly.
Will this work with my existing codebase, or do I need to start from scratch?
I integrate directly into your existing project. You don't need to rebuild anything. I review your current structure first and build the auth system to fit your stack — whether that's a React frontend with a Node.js backend, a Next.js full-stack app, or a Firebase project.
How do you handle security?
I've seen developers just copy tutorials. Everything I deliver follows OWASP authentication standards. That means bcrypt password hashing with proper salt rounds, HTTP-only cookies or secure token storage, rate limiting on login endpoints, brute-force protection, and zero hardcoded secrets — all co
What exactly is role-based access control, and do I need it?
Role-based access control (RBAC) means different users get different permissions — an admin can delete users, a regular user can only view their own data, a moderator can approve content but not access billing.
Will you need access to my database or secret keys?
I work with the minimum access needed to get the job done. For most integrations I only need your project repo. When environment variables or API keys are involved, I'll guide you on how to share them securely — never over chat, never stored anywhere after delivery. Your credentials stay yours.
What if something breaks after delivery?
Every package includes free minor revisions after delivery. If a bug is directly related to the auth system I built, I fix it at no extra charge. I also deliver clean, documented code — so if you or your team need to make changes later, you'll understand exactly how everything works.
