Role-Based Login System in CodeIgniter 4: Admin & User Roles – Best for Small Projects?

Securing user access is a critical step in any web application, especially when different users need different levels of control. CodeIgniter 4 (CI4), known for its lightweight footprint and speed, is an excellent choice for implementing role-based access control (RBAC) in small to mid-size projects. In this hands-on tutorial, we will build a complete role-based login system from scratch in CodeIgniter 4 — covering database setup with migrations, user authentication with hashed passwords, session-based role management, route-level middleware filters, and separate admin and user dashboards. Whether you are building a blog, internal tool, or small e-commerce app, this guide gives you full control over authentication without the overhead of third-party libraries.
