Can't change user ID on PS4

[patseguin]

Hmm sounds odd... well I know as I swaped PC to PS4 i had to buy game for Playstation and add on Mogstation a Playstation licence (still have PC escape when PSN bugs out \o/) If you done that I seriously dont know as I have like on PC the loginscreen where I type in ID, PW, onetime PW :/

I don't see anything about adding a license on mogstation. I purchased the game on the PSN store, I don't buy any physical media anymore. It doesn't come with any license.
