Improved Photo Privacy
As of right now, sharing your photo library with third-party apps is an all-or-nothing proposition. An app asks to access your photos, you grant access, and that app gets full access, whether you like it or not.
However, it looks like iOS 14 is set to clamp down on this, with a new “Limited Photos library access” feature that will let you choose to share only individual selected items with an app that asks for access to your photos. So, for example, when sharing a photo on Instagram, Twitter, or Facebook, you can choose to grant access to only those photos you want to share without worrying that the app could be scooping up other photos.
