Let me help you, Bgain. I'll share a few reasons why you're required to sign in.
Once a user is logged in with a Windows user account, they will be required to enter a username and password to log in. Also, if a user has saved credentials for a company file user in QuickBooks File Manager, opening the file from QFM will delete credentials from the Windows vault. You'll be required again to enter a username and password.
We're unable to stop this. However, you can stay logged in to your company file without entering your credentials every time. For more information, you can check this article: Stay logged in to QuickBooks company file (sign in without entering your password).
