Good day, Ellen108.
Thanks for bringing this to our attention. I'm here to make sure your bookkeeper gets access and sign in to QuickBooks Desktop (QBDT).
If you're the Administrator, you can reset the bookkeeper's password by editing his/her profile. To do this task, please follow these steps:
I've attached some screenshots below to help you with the process.
For further guidance, refer to this article that will help: Reset your password for QBDT.
This should get your bookkeeper signed in to your company file and get back to business. Leave a comment below on how it goes. I'll be around to keep helping.
