Hello, I have a question about authentication across multiple servers using playfab. My game is supposed to use playfab mainly for auth, photon server (on-premises) for multiplayer and mysql database on another server.
What i want to achieve is client connects via playfab then i connect to photon server using PlayFabID as a userID and the photon server later manages mysql database based on userID (PlayFabID). Also i want my client to connect to mysql database (via php) in the same manner (using PlayFabID).
I guess it works, but it seems highly unsecure since someone can connect to mySQL database and photon server if he only knows a certain PlayFabID without logging to playfab.
Im not too familiar with authentications and stuff, so here is my question. How can I make a validation and make all these connections safe.
