Lots of folks using WordPress sites with multiple authors may run into this problem. You want to attribute correct credit to the writer/author of the article, but not give out access to your WordPress install. Maybe because it’s a one-time article, maybe not, who cares?

If the author of your blog entry (or page or custom post type) is different than your logged in user and you don’t want to have to create a separate user account, just add the name as you’d like it to appear to the Custom Author Byline panel below the post editor. Easy!

Download the plugin!

Installation

1. Unzip the downloaded plugin file `custom-author-byline.zip`,
2. Upload `custom-author-byline.php` to the `/wp-content/plugins/` directory,
3. Activate the plugin “Custom Author Byline” through the ‘Plugins’ menu in WordPress
4. That’s it! You will now see a new panel below your post/page editor where you can type in whatever name you want to appear in place of your logged in user.

Updates

Version 1.2 (Released 2011-06-08)
Added support for pages and custom post types (post types requires a more advanced user at the moment) and the ability to add a custom URI for the custom author. The custom URI bit was added by request of commenters below. Neat!

Version 1.1
Renamed all the functions in the plugin to eliminate some conflicts with other plugins.

Version 1.0
New release.

Coming Soon

Adding custom post type support from the admin area. (Currently you have to either edit the plugin and uncomment some code and/or add the code to your theme functions.php file.)
