Thanks for dropping your concern here in the Community space, Bret. Let me assist you with the logout duration when working with QuickBooks Online (QBO).
For security, QBO has built a logout timeframe duration every time you're inactive using it. The default setting is 1 hour, but you can change it to 3 hours. I'll show you how:
In Settings, click Account and Settings and choose Advance.
From the Other Preferences section, select Edit.
Decide from 1, 2 or 3 hours from the Sign me out if inactive for dropdown menu.
