TGTs across Devices.

I have an app (Android) using Kerberos 5 to get a TGT. If i login to that app on 2 separate devices using the same account, does each device generate a separate TGT and thus session, or does device 2, get a copy of the first device's TGT?

EDIT:

This is hitting a Windows Server 2008, with i believe largely all the default settings.
