Thank you for posting your signing issues here with your QuickBooks Desktop (QBDT), Angie.
There are two types of user modes in QBDT - Single User and Multi User. In a single user, only one computer may access your company file, however, in multi-user mode, it is possible to log on simultaneously to multiple computers.
