Yes. I think you can have up to three on one login.
Sounds great! Thanks for the info
Also I just found this on the KDP board:
Here is the procedure from KDP Support:
Author Central allows you to manage up to three Author Pages within a single account. If you write under your real name as well as a pseudonym, you can manage both Author Pages from the same Author Central account. Here's how:
1. Log in to Author Central (https://authorcentral.amazon.com).
2. Click the "Books" tab located on the top of the page.
3. Click on the "Add more books" link that appears under "Are we missing a book?"
4. Search for books written by Nom de Plume by title, author, or ISBN.
5. Click "This is my book."
