For security purposes, MicroBiz Cloud will automatically log you out if you are inactive for 1 hour.  

To modify the default time you can follow these steps:

From Store Operations go to the Settings tab and select  Admin Settings.

On the left hand side you will need to  click on Default Setting and then Users.

The default time is set for 3600 seconds (one hour).  Eight hours would be 28800 seconds..

Click on Save to make your changes permanent.
