@manualdousuario @deadsuperhero @news Author handling can be set up in multiple ways. Either there is one blog-wide handle, or individual handles for each author, or both (authors publish under their handles, automated blogwide handle boosts them).
Author profile (profile pic, bio, header image) can be set up as well. Now I see they also support profile aliases used for account migration but I have not tried that yet and would be careful.
My wp profile is @fifisch@fifijezase.online
I'm not sure if I'm federated to mastodon.social instance yet, but my guess is you should be able to see at least the two most recent posts...
