My site is built in PHP and runs smoothly, but it still lacks a proper authentication layer. I now want to extend the codebase by introducing a full-featured user login system with multiple permission tiers—admin, editor, and standard member. Here is what I need from you: • Clean, secure registration and login flows (password hashing, session handling, CSRF protection). • Role-based access control so each level only sees and edits what it should. • Simple-to-use admin dashboard to manage users, reset passwords, and promote or demote accounts. • Well-commented PHP code that plugs into my current structure without breaking existing pages. • A short read-me describing any database changes and how to deploy the update on staging and production. I am happy to give you direct access to a cloned staging environment plus an SQL dump so you can work without touching live data. If you prefer specific libraries such as Laravel’s built-in auth or a lightweight custom solution, just outline your approach. Security, clarity, and maintainability are my top priorities. Let me know your estimated turnaround and what you need to get started, and we can begin right away.
