Gatekeeper: An Authentication & Authorization Library
The Gatekeeper library is a simple drop-in library that can be used to manage users, permissions and groups for your application. The goal is to make securing your application as simple as possible while still providing a solid and secure foundation to base your user system around.
Gatekeeper is best classified as a Role-Base Access Control (RBAC) system with users, groups and permissions. It is framework-agnostic and is set up to use its own database for the user handling.
