I will build a secure nodejs jwt authentication and login system


About this gig
Need to protect user accounts, prevent unauthorized access, and manage login sessions securely?
I build secure nodejs jwt authentication and login system & express js auth APIs for SaaS, startups & eCommerce. Production-ready backend security.
Problems I Solve:
- Insecure logins & password handling
- Broken tokens & sudden logouts
- Refresh-token reuse & session leaks
- Missing admin/reset controls
- Unauthorized API access
Basic Package:
- Native jwt authentication & access tokens
- Bcrypt password hashing
- Strict Joi data validation
- Profile endpoint (/me)
- Centralized errors & Helmet security
Standard Package:
- Everything in Basic
- Opaque refresh-token rotation & revocation
- Token reuse detection
- Secure email password-reset flows
- Admin user controls with pagination
Premium Package:
- Everything in Standard
- Role based access control (RBAC)
- Two-Factor Authentication (2FA)
- Secure Email Verification checks
- Active session tracking & device revocation
- Security event logs & failed-login lockouts
- Production oauth integration (Google/GitHub)
Tech Stack: Node.js, Express, MongoDB, Mongoose, JWT, Joi.
Backend REST APIs only. No frontend UI development.

FAQ
Is the basic package safe from modern web vulnerabilities?
Absolutely. Even in the Basic tier, passwords are never stored in plain text; they are secured using strong Bcrypt hashing. For enterprise-grade protection against XSS and session hijacking, the Standard and Premium packages utilize secure HttpOnly, SameSite cookies.
Does this gig include a frontend UI or dashboard design?
No, this gig is strictly for backend REST API development. I will build a secure express js api layer with clean database logic, but you or your team will need to create the frontend UI components to connect to these endpoints.
Which package includes social login like Google or GitHub OAuth?
Production-ready oauth integration (Google and GitHub social logins) is exclusively included in the Premium Package, alongside other advanced server configurations like failed-login lockouts and active session tracking.
Can I restrict certain API routes to Admin users only?
Yes, this is handled through advanced role based access control (RBAC). Available in the Premium tier, this middleware dynamically checks user roles in MongoDB to protect administrative actions and prevent unauthorized access to sensitive endpoints.
How does the refresh-token rotation and reuse detection protect my app?
It is an elite security feature included in the Standard and Premium packages. If an old or intercepted refresh token is reused, the nodejs login system immediately flags the threat, invalidates the entire token family, and forces a logout to lock out the attacker.
What do I receive upon project completion to help me connect my frontend?
You will receive a clean, zip file of the modular codebase organized in an MVC pattern (Routes, Controllers, Models, Middlewares), along with a pre-configured Postman Collection. Your frontend developers can import this collection to test and integrate every single secure route instantly.
