When using Abtrac two factor authentication, a code will be sent to the user’s email address which is required to be entered before gaining access to Abtrac. This will confirm the device they are working on is a trusted device.
Each user can opt to remember this device for 30 days or they can get a new code every time they login in.
This is an added level of security you can opt in to enable from Administration > Settings > System Settings > Employee section of Abtrac.

You can also add and remove this setting for individual users from the Employee Login management Screen Administration > Employees > Login Management
