In my firebase app, a users feed is populated with posts, however the usernames of the posts are displayed. However, the username is inside of the snapshot, but there is no place where it is displayed in the app. Is it secure to have the username transferred to the client's device if they are not supposed to be able to access it? Would it be better to remove the username from the snapshot in the posts node and instead create a separate node which has the username for each post, accessing the username each time it is needed so that when a users feed is populated the username is not sent in the snapshot?
