It's my top priority to let you log into your QuickBooks Desktop (QBDT) account so you can get back to business in no time, @David741.

Before we start, I'd like to verify if you've encountered an error while logging into your QBDT account? Any additional details will surely help me in providing the appropriate resolution for this matter.

Let's start by resetting your admin password so you can log in to your company file. This process will let you confirm some information for security purposes. You may log in to your Customer Account Management Portal (CAMPS) account to verify and gather all the data you need. Then follow these steps:

1. Open QuickBooks Desktop (QBDT).
2. Click the I forgot my password link in the QuickBooks Desktop Login window. 
3. Fill out the required information on the form, such as license number, name, email address, phone number, and other information. 
4. Once ready, click OK. 

Once you're done, you’ll receive a code at your registered email address and use it through in creating a new admin password.

In case the process above doesn't work, please double-check the info you've entered. Make sure they match with what's in CAMPS. Then, you can utilize our Automated Password Reset Tool once you're still getting an error or needs further help with your password. For the step-by-step guide, you can refer to this article:  Use the Automated Password Reset Tool for QuickBooks Desktop.

Also, to further guide you in managing your QBDT account (i.e., company info, data and security, and user management), I'd recommend checking out this article: QuickBooks Help Articles.

Please know that you can always get back to this post if you have any other login concerns in QBDT. I'll keep an eye on your response and gladly help. Take care, and have a good one, @David741.
