In macOS are implemented the so-called keychains (key-password bindings, storage and access to which macOS provides).
For example Paragon NTFS for Mac App has its bindings created as soon as you log in to your MyParagon account, because NTFS for Mac has always access to this keychain.
But other applications may require user confirmation.
That is what happens when you run Paragon ExtFS for Mac App.
Just click “Allow” or “Always Allow” for not to be bothered again by this notification.
