The game account on the other device should be linked to a Kabam ID account, then on your main device you can just login to that other Kabam ID account in order to play that other account.
If it was not linked to a Kabam ID originally (or since then yet), you can create one on that device and then link that game account to it. Then it will be ready to play on your main device by logging into it within game (settings - login). See Kabam tips for creating and linking a Kabam ID.
