It is possible to play with the same account on the Windows®, PlayStation®3, and PlayStation®4 platforms. Customers who own a copy of FFXIV for Windows® and wish to use their account on the PlayStation®3 or PlayStation®4 version will need to purchase an additional copy for the desired platform. In order to use your characters on multiple platforms, you must tie your existing service account to the PlayStation®3 or PlayStation®4 version upon launching the game on that platform for the first time. Similarly, customers who own a copy of FFXIV for the PlayStation®3 or PlayStation®4 and wish to use their account on the Windows® version will need to purchase a copy of the Windows® version. However, please note that your account will only be able to log in to one platform at a time.
