My title supports local and online multiplayer splitscreen.
How can I support this on Playfab?
For example:
On Xbox or Playstation, I want to be able to have multiple users signed in to XBL or PSN at once on a single machine.
Does Playfab support this?
PlayFab does not support multi-user sign in one device, but you can modify SDK to record multiple player's Session Tickets to reach it. There is a thread you can get more information from: https://community.playfab.com/questions/10901/multiple-accounts-on-one-device.html
Thanks Hernando.
That's helpful, I can certainly keep the Session Tickets for each user but I can't use that matchmaking I think?
The apis for CreateMatchmakingTicket() and GetMatchmakingTicket() don't accept Session Tickets but player entityToken for the creation call. So I guess this doesn't work with matchmaking?
I have another post awaiting moderation that goes into greater detail.
No worries - you can get Entity Tokens from Session Tickets (https://api.playfab.com/documentation/Authentication/method/GetEntityToken).
Looks to me like it doesn't when it comes to matchmaking?
I've been working my way through the quick start guide here:
https://docs.microsoft.com/en-gb/gaming/playfab/features/multiplayer/matchmaking/quickstart
I'm currently using LoginWithCustomID() and have logged in multiple users.
I create a matchmaking ticket successfully using PlayFab::PlayFabMultiplayerAPI::CreateMatchmakingTicket().
Then I try to get a matching ticket using PlayFabMultiplayerAPI::GetMatchmakingTicket().
This calls my callback with 'WaitingForMatch' correctly when only one user has logged in but when multiple users call LoginWithCustomID(), this then fails with:
PlayFabErrorMatchmakingUnauthorized (2056)
"MatchmakingUnauthorized"
"Only a user in the ticket can access it."
I assume I'm doing something wrong here but I can't see how else I can have multiple authenticated users.

Depending on which SDK you're using, you can try out the new instanced API classes. It looks like you're using the cpp sdk. You can try out the new PlayFabMultiplayerInstanceApi:
https://github.com/PlayFab/XPlatCppSdk/blob/master/code/include/playfab/PlayFabMultiplayerInstanceApi.h. That allows settings to be cached independently for each instance, so you'd have one per player. Those are fairly new, so let us know how it goes.
