Linking two PS4 copies of the game to the same PSN account

Hey,

Is it possible to buy two copies of the game and play on the same psn account with two different square accounts?

A friend lost her login details, or rather, the game said they were incorrect and wouldn't let her in anymore, and after a while it said there was no account registered to that e-mail address at all. She sent a support ticket for that, but in the meantime she's planning to buy a second copy and start over. Is that possible on the same ps4/psn account?

In short - no - you can register only one copy per platform (PS3 or PS4). She would need to create another PSN account and link it to separate SE service account.
