I am new to programming and I am making a login/pass authentication system for a project in Code Igniter. I can simply secure pages by setting session and then giving access based on whether the session is set or not ... Before I jump into it ... I see many auth libraries around .. like tank auth, ion auth and so on.
My question is, why would anyone use Auth libraries? If my app is simple which means there will be just one kind of user with same permissions, do I still need Auth lib like Ion Auth?
