Hi
I set a unique id with my custom login system for each player that wants to enter into my game and join to SqlLobby.but the player still could connect to my photon server in other devices by the same id.
Is there any way that to restrict joining to lobby by unique id?

Hi @atworld,
Thank you for choosing Photon!
We already restrict one actor per UserID inside rooms usingRoomOptions.CheckUserOnJoin = true.
To allow only one client per UserID on Master Server you need to:
- use custom authentication and implement a session system on your web server (tricky for unexpected disconnects) or
- modify LoadBalancing server code0 -
Hi, @atworld
UPDATE:
our web hooks are limited. so you could not implement this using your own plugin. or WebRPC for instance together with WebHooks. WebHooks will mark player as online somewhere in your backend. and webrpc may as your backend and block player if it is already online
but be very carryfull to not block just reconnecting players. you will need to use some kind of session id.
best,

Hi @atworld,
I have some modification to LoadBalancer to block more than 1 connect per user with CustomAuthentication.
1. function DoCustomAuthenticationResult In the MasterClientPeer.cs
case CustomAuthenticationResultCode.Ok:
//apply user id from custom auth result
if (!string.IsNullOrEmpty(customAuthResult.UserId))
{
// SnowCat check whether user is online. disconnect if it is.
var app = (MasterApplication)ApplicationBase.Instance;
if (app.DefaultApplication.PlayerOnlineCache != null && app.DefaultApplication.PlayerOnlineCache.IsPlayerCached(customAuthResult.UserId) )
{
operationResponse.ReturnCode = (short)Photon.Common.ErrorCode.CustomAuthenticationFailed;
operationResponse.DebugMessage = "Player already online";
this.SendOperationResponse(operationResponse, sendParameters);
this.SetCurrentOperationHandler(OperationHandlerInitial.Instance);
return;
}
// SnowCat Change End
this.UserId = customAuthResult.UserId;
}
else if (!string.IsNullOrEmpty(authRequest.UserId))
{
this.UserId = authRequest.UserId;
}
else
{
this.UserId = Guid.NewGuid().ToString();
}
2. Add a funtion to class PlayerCache in PlayerCache.cs
// SnowCat add some support to query player with id
public bool IsPlayerCached(string playerId)
{
return this.playerDict.ContainsKey(playerId);
}
// SnowCat change end
Those codes will block user with SAME UserID connect more than once.3
