Thanks for joining us here in the thread, @mfrumento. It'll be my pleasure to share some details as to why QuickBooks wants you to sign in your Intuit account.
To start off, when you create a new company file, you'll need to use an intuit account to sign in. You'll need to do this if you use a connected service like Payments, T-sheets, Payroll, or Receipt Management.
Using an Intuit account is different from your QuickBooks company file login. A QuickBooks Company file login gives you access to basic features like paying a bill or creating an invoice. Whereas if you're using an Intuit account, this gives you the access to all connected Intuit services for your company file.

In case you don't have an Intuit account yet, here's an article that'll guide you on creating your account: Create an Intuit user account.
