AuthHive

Centralised authentication for multiple applications

A standalone authentication service built with Node.js and Hapi.js, providing secure authentication, session management, and single sign-on across connected applications.

01

The challenge

Managing authentication independently across applications creates duplicated logic, inconsistent sessions, and security vulnerabilities that are difficult to maintain.

02

The approach

I developed a centralised authentication service using Hapi.js, JWT access tokens, refresh-token rotation, Redis session management, PostgreSQL, and endpoint-level rate limiting.

03

The outcome

A reusable authentication infrastructure that gives connected applications a consistent login experience and centralised security management.
