WordPress is the best platform for creating a website without prior knowledge of programming. In WordPress author is the user who wants to write and publish his blog on your website. Authors can publish, edit, and write their content on your website but they can’t modify other user posts. In some cases, owners of the website don't want to display the author's name but WordPress doesn’t have a default setting for removing authors from the post. The owners who don't have any technical knowledge can also remove author name from WordPress posts by using some methods which are very easy to follow. WordPress has multiple methods for it such as plugins, Manual, Schema markup, CSS and many more. By using plugins like WPCode, and Hide/Remove metadata we can easily change or remove authors from sites.
