Instagram is reportedly testing a new feature that allows users to lock their Reels, making them visible only to select viewers. Locked Reels will appear blurred on profiles, requiring a secret code for access. This code can be anything the creator chooses, potentially increasing engagement through trivia or personal themes. Instagram's Design account hinted that the first hashtag in a caption could serve as the unlocking code. This feature is part of several updates Instagram is exploring, including new messaging capabilities and a possible 'Dislike' button for posts.
