In order for your GF to play they will have to either start a trial account, using the trial version of the game as previously mentioned. Or create a brand new Service account on the Mogstation or via the start-up on a new game, and add a new Game key(from a new purchased game) to that service account on the Mogstation. It is against TOS to share any one account.
Thanks all for the helpful replies. I think I will start her off with a trial account on the ps4.
Will I have to redownload the game for her if it's already on my psn account?
