Thanks for joining in on the thread, LindaKP1023.
With QuickBooks File Manager, you can mange your passwords through the Password Vault. This is also the possible reason why it requires you to enter the username and password. It is aligned with what Ashley H said in her response: https://quickbooks.intuit.com/learn-support/en-us/install/re-quickbooks-file-manager/01/516145/highl....
You can use this link on how you can manage your Password Vault: Learn the basics about QuickBooks File Manager.
I'd also recommend keeping your QuickBooks release version up to date to get rid of any minor issues.
If the same thing happens, you can contact our Technical Support Team by following the steps provided MaryLandT. Or you can follow this link.
Let us know how this goes so we can also review it on our end. Have a great day!
