That should ba a native function in WordPress including, byline modification and possible translation. Meta tags for authors, editors, reviewers shall be added.

Hi and welcome back to WordPress Trac!

As noted on ticket:48023#comment:1, there has been discussion about adding this functionality to core (which was considered plugin territory more than ten years ago). Let's keep that conversation on #7650.

Even if we reopen the ticket, it likely will not be completed soon. So you probably want to look into plugin options for your own site(s).

• ​Co-Authors Plus adds the basic functionality, and WPBeginner helps describe how to ​edit the theme template files to work with the plugin.
• ​PublishPress Authors includes the functionality, plus it can display multiple authors on the post without requiring any theme changes (though you may want to customize the styles).
