Hello there, @mbesso.

The QuickBooks Desktop (QBDT) program is making sure your account and company files are protected at all times. That's why it lets you log into it for additional security protocol. You can learn more about this by checking out this article: Password security for QuickBooks Desktop. It also includes answers to the most frequently asked questions about the topic.

Additionally, you're able to switch your company files without having to re-enter your login credentials every time. To learn more about this, I'd recommend pulling up this article: Stay logged in to QuickBooks company file (sign in without entering your password). It contains details about things to consider, login settings, and notes for each user to name a few.

Please know that you're always welcome to comment below if you have other concerns or follow-up inquiries about managing the growth of your business and security protocols in QBDT. I'm just around to help. Take care.
