Rift CE authenticates each account through the Roblox authentication API to obtain a short-lived auth ticket, then constructs a roblox-player:// deep-link URL and hands it to the OS to open Roblox. This works without storing any session cookies in the Roblox client itself — each launch is independent.

​
Basic launch flow

1

Select an account

Click an account row in the account list to select it.
2

Click Launch

Press the Launch button. With no place ID specified, Rift CE opens Roblox home for the account.
3

Auth ticket is fetched

Rift CE sends a POST to https://auth.roblox.com/v1/authentication-ticket with the account’s .ROBLOSECURITY cookie. The rbx-authentication-ticket response header value is extracted and embedded in the launch URL.
4

Roblox opens

The OS handles the roblox-player:// URL and starts the Roblox client. LastUsed is updated and saved to the vault.

​
Launch URL structure

The exact URL format used by RobloxLauncher varies by launch type.
Opens Roblox home without joining any game.
roblox-player:1+launchmode:app+gameinfo:{ticket}+launchtime:{timestamp}

​
Joining a specific game

To launch an account directly into a place, provide a Place ID in the launch dialog. You can optionally provide a Job ID to target a specific server instance.

​
VIP servers

To join a VIP server, prefix the Job ID field with VIP: followed by the VIP server access code: 
VIP:abc123def456
Rift CE detects the VIP: prefix and routes the launch through the accessCode / linkCode query parameters instead of gameId: 
if (jobId.StartsWith("VIP:", StringComparison.OrdinalIgnoreCase))
{
    var accessCode = jobId[4..];
    launchUrl += $"&accessCode={accessCode}&linkCode={accessCode}";
}

​
Multi-account launch

LaunchMultipleAsync iterates over a list of accounts and launches each one sequentially, waiting between each launch for the duration configured in Settings → Join Delay (in seconds). 
public async Task LaunchMultipleAsync(
    IEnumerable<Account> accounts, long placeId, string jobId = "")
{
    var delay = App.Settings.JoinDelay;
    foreach (var account in accounts)
    {
        await LaunchAsync(account, placeId, jobId);
        if (delay > 0)
            await Task.Delay(delay * 1000);
    }
}
Select multiple accounts in the account list, then click Launch All to launch them into the same place. The join delay prevents Roblox’s servers from rate-limiting rapid join requests.

​
Follow user

The Follow feature looks up a target user’s current game presence via https://presence.roblox.com/v1/presence/users and joins the same server instance. 
public async Task<bool> FollowUserAsync(Account account, long targetUserId)
If the target user is not currently in a game, the launch is aborted and the LaunchCompleted event fires with a failure message.

​
FPS unlock

When Settings → Unlock FPS is enabled, Rift CE patches the Roblox client settings file before each launch via ClientSettingsPatcher.PatchFpsUnlock(App.Settings.MaxFps). Set your desired frame rate cap in Settings → Max FPS.

​
Multi-Roblox

Running more than one Roblox client at a time requires removing the singleton mutex that Roblox creates to prevent multiple instances. Enable Settings → Multi-Roblox and Rift CE will call RobloxMutexHelper.KillSingletonMutex() before each launch.
Multi-Roblox works by killing the Roblox singleton mutex immediately before each new launch. Disable this setting if you only ever run one account at a time — it avoids unnecessary process enumeration on every launch.

​
Launch events

RobloxLauncher exposes two events you can subscribe to for status feedback:
EventSignatureFires when
LaunchStartedAction<Account, string>The launch sequence begins. The string is a short status message such as "Joining 12345...".
LaunchCompletedAction<Account, bool, string>The launch succeeds or fails. The bool indicates success; the string contains a result message.
