I appreciate your prompt response, @mox.

Allow me to step into this conversation and provide you with some clarifications about setting up passwords in QuickBooks Desktop.

You'll need to set up passwords for each of your company files in QuickBooks Desktop. However, you have the option to set the same password for all of your files so it would be easier for you to remember. 

To give you more information about having a good and secure password in QuickBooks, you may read through this article: Password security for QuickBooks Desktop.

If you need additional assistance with this process, I'd suggest reaching out to our Customer Care Team. You can reach them through this link: Contact the QuickBooks Desktop Customer Support Team.

Please let me know how it goes, or if you have any other concerns with QuickBooks. I'd be happy to help. Wishing you and your business continued success.
