To change the author ID (attribution) on all posts in a single pass in WordPress, you can use the following steps:
- Log in to your WordPress site as an administrator.
- Navigate to the WordPress Dashboard and select “Posts” from the menu on the left side.
- Select all posts by clicking the checkbox next to the “Title” column header.
- From the “Bulk Actions” dropdown menu, select “Edit.”
- In the “Author” section, select the desired author from the dropdown menu.
- Click the “Update” button to apply the change to all selected posts.
This will change the author ID (attribution) on all selected posts to the new author in a single pass. Note that this process cannot be undone, so make sure to backup your data before proceeding.
