i can do paralle login using same user name and password from different computer. and it works.
game1: logged in with "user1" and pass "zzz"
game2: logged in with "user1" and pass "zzz"
how to prevent that?
but in which cloud event i need to put it?
If I had to guess, I'd say "Player Connected", but I'm not sure if that code is run before or after establishing the connection with the new player. I'd be afraid of just always terminating the connection with a player.
Give it a test and see what happens?
It would be best placed in the cloud code of your authentication Response.
