Hello there, lari.
We're unable to track login/logoff dates of users in our company file. I'll surely send this feedback to our engineers so they can add this option on our next updates.
The Audit Trail report lists each accounting transaction and any additions, deletions, or modifications that affect that transaction. It sorted by the user who created or last modified the transaction, the transaction type, and the date the transaction was created or last modified. We can use the Entered/Last Modified and State column to help us identify when was the first and last time the user did an activity within our books.
To know more on how to customize the Audit Trail report, you can use this article as a reference: Customize reports in QuickBooks Desktop.
Let me know if you need anything else. I'm here to help. You take care always!
