How To Run Multiple Roblox Accounts at Once (2025 Guide)

How To Run Multiple Roblox Accounts At The Same Time! — Use Process Explorer to close the ROBLOX_singletonEvent handle after launching your first client, then open additional sessions on alt accounts; or, install both the Microsoft Store app and the desktop Roblox Player to run two distinct clients side‑by‑side without touching handles. Admin rights are required to handle edits, multi‑instance tools like Bloxstrap’s option can help but break after updates, and stability improves if the first window stays open while you launch the next.

Method 1: Process Explorer (singleton handle)

• Download Process Explorer from the official Microsoft Sysinternals page and run it as Administrator so it can manage process handles.​​
• Launch your first Roblox account, then in Process Explorer search for “Roblox” and select RobloxPlayerBeta.exe to view its open handles.​
• Locate the handle named “Roblox Singleton Event” (often shown as ROBLOX_singletonEvent), click it, and choose “Close Handle” to remove the single‑instance lock.​​
• Start a second Roblox session on another account, and repeat the close‑handle step if opening additional instances fails after subsequent launches.​
• Keep the original window alive; closing the first client that had its handle removed may terminate the later windows due to dependency on the initial process state.​

Method 2: Two official clients (no tools)

• Install both the Microsoft Store Roblox app and the desktop “Roblox Player” from the website so you have two distinct clients on the same PC.​​
• Log in to different accounts in each client and launch experiences in parallel; this dual‑client method is easy and avoids handle editing.​​
• Expect extra CPU/GPU load when running two app types at once; if performance dips, prefer this method over multi‑instance tools on lower‑end systems.​

Method 3: Multi‑instance helpers (optional)

• Community utilities such as MultiRoblox/Bloxstrap “Multi Instance” automate the same outcome by bypassing the singleton lock without manually hunting the handle.​​
• These tools can break after platform updates or anti‑tamper changes, so keep a fallback like Process Explorer or the dual‑client approach ready.

Quick setup checklist

• Prep: Install Process Explorer, or install both Store app + desktop Player if you prefer the no‑tools path.​
• Launch: Open first account, remove the ROBLOX_singletonEvent handle (Method 1) or open the second client type (Method 2), then log in and join.​​
• Repeat: For more windows, repeat the handle‑close step per new launch (Method 1) or mix in multi‑instance tools if desired.​​

Troubleshooting and tips

• Admin rights are required for Process Explorer to close protected handles; if the handle doesn’t disappear, re‑run as Administrator and try again.​​
• If additional clients instantly close, confirm the singleton handle was closed on the currently active RobloxPlayerBeta.exe and that the first window remains open.​​
• For window control and workload balance, the Store‑app + desktop‑app combo lets you resize and arrange side‑by‑side with minimal friction.​
• Maximum instance count is hardware‑limited; creators demonstrate 3+ accounts on modest PCs, but performance scaling depends on CPU/GPU and memory.​​

FAQ

• What is the “singleton” event? It’s an internal one‑instance guard; closing the ROBLOX_singletonEvent handle removes that guard so another client can start.​
• Is there an official way? The easiest “official” path is two client types (Store app + desktop Player), which avoids manipulating process handles entirely.​​

Step‑by‑step (Process Explorer, condensed)

• Open Process Explorer as Admin → search “Roblox” → select RobloxPlayerBeta.exe → find “Roblox Singleton Event/ROBLOX_singletonEvent” → Close Handle → launch another account window.​​

Step‑by‑step (Two clients, condensed)

• Install Microsoft Store Roblox app and the desktop Roblox Player → log into different accounts in each → start both experiences side‑by‑side.​​
