Fine-grained access control allows for more precise management of access permissions, and grants or denies access based on multiple factors. This method provides precise control over who can access what data or functionalities, and becomes particularly important when dealing with access to specific data or in complex circumstances - where you might have more than one account. Imagine a library where access to each section and book is individually controlled. Some books may only be available to specific membership types, and users may need different permissions to borrow books or access special collections.
