Hi there, @mkc54.
Thanks for joining the Community. I'd be happy to walk you through on how you can set up an admin name and password in QuickBooks Desktop.
Have you successfully logged in into your QuickBooks Desktop? If so, you can set up an admin name and password under the Company section.
To learn more about setting up user roles and restrictions in QuickBooks, you may read through this article: QuickBooks Desktop Users and Restrictions.
That should do it!
You've got me here if you have any follow up questions about setting up admin name and password in Quickbooks Desktop. I'd be pleased to help you out. Have a good one!
