Access Types 

An access type is a single, self-contained rule that can grant access to a protected folder. Every access type answers one simple question for a given protection record: "Should the current visitor be allowed in?"

When a folder is requested, fp-fileprotector asks every registered access type in turn. Access is granted as soon as one access type grants it — the access types are combined with an OR conjunction. If no access type grants access, the request is denied.

fp-fileprotector ships with two access types out of the box:

Frontend Login 

Grant access to logged-in frontend users, optionally limited to specific users or user groups.

Backend Login 

Grant access to backend users based on their own file storage permissions.

You are not limited to these two access types. See For Developers to learn how to add your own.
