Authentication and Login Development
Sign-up, login, and session handling built properly: passwords stored correctly, sessions that expire the way they should, and roles enforced on the server, not just hidden in the interface.
What we can help withWhat We Can Help With
- Email & Password Auth
- Social Login (Google, Apple, etc.)
- Magic Link Login
- Multi-Factor Authentication
- Role-Based Access Control
- Single Sign-On (SSO)
- Session Management
- Auth for Mobile Apps
What you getWhat the work actually includes
Sign-up and login flows
Email and password, magic links, or social login, with verification and password reset handled securely.
Session and token management
Sessions or JWTs with proper expiry and refresh handling, so a stolen token does not grant indefinite access.
Role-based access control
Permissions checked server-side on every route, with an admin surface to manage roles.
Multi-factor authentication
TOTP or SMS-based second factor, for products where a password alone is not enough.
ToolingWhat we build it with
Chosen because it fits the problem, and because you will be able to hire someone who knows it after we hand over.
- Node.js
- OAuth
- JWT
- PostgreSQL
QuestionsAuthentication & Login, answered plainly
Should we build auth ourselves or use a provider?
A managed provider (Auth0, Clerk, or similar) for most products — it removes an entire security surface you would otherwise own. We build it in-house when you need full control over the data or a flow the providers do not support.
Can you add social login to an app that already has email/password?
Yes, and accounts can usually be linked by verified email so a user does not end up with two separate accounts by mistake.
Can you audit our existing authentication for security issues?
Yes. A short paid review covering password storage, session handling, and whether authorization is actually enforced server-side, with a prioritised list of what needs fixing.
Related workWhat else we build
Most projects need more than one of these, and they are usually cheaper together than sequenced apart.
