Google Photos is a great product but for me it has one huge drawback. You cannot remove a person from a shared album after adding them. You or anyone an album is shared with can accidentally share the album with any other person and once that happens, only way to stop them from accessing your photos is to delete the whole album. Deleting the album means losing all photos, comments and likes added by others. Also sharing an album always generates a link that can be used by anyone to access the album. I haven't found a way to share only with people without generating the link.
