Currently I play on PC. My gf decided she wanted to play ffxiv too she I let her take my ps4 and she bought her own copy of ffxiv and downloaded it onto the ps4 so we could play. She bought ffxiv on my ps4, while logged into my PSN name.

We want to buy an additional ps4 now so we each can have our own ps4 and I can buy a copy of ffxiv and I can swap between ps4 and PC. Can I go back to using my old ps4 and my original psn name and log in to play, and she can have the new ps4 and create her own psn name and continue to play her character? This way she can have her own friends list on psn etc..Or is her account tied directly into my PSN name so she has to be on that PSN name anytime she wants to play ffxiv? Thanks in advance
