PS4 advice for a new player please

[Interrossiter]

I've been playing the trial game on PS4 & have decided to buy & as it's been so great & so will upgrade from the trial version.
I'm now logging in on a PS4 in our front room which has the client software installed but this PS4 is used by others throughout the day.
So I wondered, if there were another PS4 available in another room, is it as simple as installing the software on it too & then logging in to my Square Enix account to play the game on that PS4 when the other is not available - if so would I just download or install from disk?
I've tried to search to see if this has been raised before, but can't find anything, so thanks in advance for any help.

The only special rule when going between one PS4 platform and another PS4 platform is that you should be logged into the same PlayStation Network account from either. (Because when you register console versions, it's done through PSN.)

If you were instead wanting to switch between different types of platforms (like between the PS4 in your front room and a PS3, PC, or Mac in another room), that would require purchasing the game for each platform type and registering them to the same SE account. But that doesn't apply when it's two platforms of the same type.

I think you just have to download the FF XIV in another PS4 logged with your account (assuming you had already purchased it) Just look for it on PS Store.

Stupid mobile version doesnt have edit button.

Yeah simply install it from the disk if you bought physical copy.
