Hi, Ravi.

I've got your back in ensuring your user's username will display every time they log in.

To fix the issue, let's ensure the login settings set for a specific number of days. You can follow the steps below.

Here's how:

1. From the Edit menu, select Preferences.
2. Go to the General tab.
3. On the Company Preferences tab, go to MANAGE LOGIN SETTINGS.
4. Tick the Keep user logged in for button.
5. Set a number of days.
6. Click OK.
   
   

If the settings all good, let's fix the issue by running the Tool Hub. Here's an article for the detailed steps of the process: Fix common problems and errors with the QuickBooks Desktop Tool Hub.

I've also added this article on how to add and edit user login and restrictions: Create and manage users and roles in QuickBooks Desktop Enterprise.

I'm always around to assist you if you have other concerns in ensuring users can login swiftly.
