How do I add my authors' job titles and social profiles?

On each author's profile, under Users → Profile, Schema Pro adds an Author Markup section: a Job title, Profiles elsewhere (one full link per line) and, where the site shows avatars, Include the profile picture. Every post whose schema leaves the author to fill itself in then names that author as a person: their name, their author page, the job title, the links, the Biographical Info and Website WordPress already has, and one @id shared by all their posts. Google recommends this for article authors.

Links already typed into Yoast SEO's or Rank Math's profile fields are used as well, so nobody has to type them twice, and the section lists them with Leave these out. Each author's page can also be marked up as their profile page, with Author page markup under Site Identity → Output.

Nothing else about an account is published: not the email address, the username or the account's ID. A link that is not a web address is refused when the profile is updated, with a message naming it.
