Hello there, @Mdileo.
Thanks for joining the conversation. I’m here to provide some more information about the message you’re getting in QuickBooks.
The pop-up is a reminder from the Merchant Services Team to all QuickBooks Desktop Payments users to confirm their login credentials. This a new authentication system implemented to make payments more secure.
Since you’re using both QBDT and Intuit Payments, I recommend following the instructions provided to get you all set up. For more details, check out this link: Create and manage your Payments user ID.
That should answer your question for today. Let me know if you need anything else, I’m more than happy to help. Take care and have a great day!
