Thanks for getting back to us, @razzzy.
Since the issue persists after trying the steps on the article shared by my colleague above, I highly suggest contacting our Phone Support team. They have tools that can pull up your account in a secure environment and investigate why it keeps on asking for a password when opening QuickBooks Desktop (QBDT). They can also perform other troubleshooting steps to fix this for you.
Here's how to reach them:
- In QBDT, go to the Help menu at the top to get to the QuickBooks Desktop Help.
- Select Contact Us at the bottom to connect with our live support.
Just in case, I'll add this article for future reference: Password security for QuickBooks Desktop.
I want to make sure everything is taken care of for you, so please let me know how it goes or if you have any other concerns. I'm always here to help. Have a wonderful rest of the day!
