You can run two Roblox accounts simultaneously on one PC using the built-in multi-instance feature or by opening Roblox in two separate browsers

The simplest way to play two Roblox accounts at once is to open Roblox in two different web browsers on the same computer. Log into one account in Chrome, for example, and a second account in Firefox or Edge. Each browser maintains its own login session, so both games run side by side without interfering with each other. This method works when ready and requires no downloads or configuration.

If you prefer using the Roblox app instead of a browser, you can install multiple versions of the app or use a second user account on your Windows PC. The second approach is more involved but keeps everything organized within the Roblox app itself rather than spreading across browsers.

Key Takeaways

  • Opening Roblox in two different web browsers (Chrome and Firefox, for example) is the fastest way to run two accounts at the same time on one PC.
  • Each browser stores its own login session, so you stay logged into different accounts without being kicked out when you switch windows.
  • If you use the Roblox app, you can create a second Windows user account on your PC and log into Roblox with a different account there.
  • Your PC needs enough RAM and processing power to handle two Roblox games running together—most modern computers can manage this, but older machines may lag.
  • You control which game window is active by clicking on it; both games continue running in the background when you switch between them.

Running two accounts in separate web browsers

This is the easiest method and works on any PC with a web browser. Open your first browser (Chrome, Firefox, Edge, or Safari), go to roblox.com, and log in with your first account. Then open a second browser window—a different browser, not just a new tab in the same one—and log in with your second account. Both games will run simultaneously in their separate browser windows.

The reason you need different browsers is that most browsers share login sessions across all their tabs and windows. If you open two tabs in Chrome and log into two different accounts, the second login will automatically log out the first. Using Chrome for one account and Firefox for another avoids this problem entirely.

Once both games are running, click between the windows to control which one is active. The other game continues running in the background. You can resize the windows side by side so you can see both games at once, or maximize one and switch back and forth as needed.

Using the Roblox app with a second Windows user account

If you prefer the Roblox app over a web browser, you can create a separate Windows user account on your PC and log into the Roblox app there with your second account. This keeps both accounts within the app rather than mixing browsers and the app.

To do this, open Windows Settings, go to Accounts, and select "Family & other users" (or "Other users" on older Windows versions). Click "Add account" and follow the prompts to create a new local Windows user. Once the new account is created, switch to it by clicking your user icon in the bottom left corner of the Windows taskbar and selecting the new account name.

Log into the Roblox app with your second account while using this new Windows user. Then switch back to your main Windows account to play with your first account. You can run both at the same time by opening the Roblox app in each Windows user session, though you will need to switch between user accounts to control each game. This method is more cumbersome than using two browsers, but it keeps everything within the Roblox app if that is your preference.

Making sure your PC can handle two games running together

Running two Roblox games at once uses more RAM and processing power than running one. Most modern PCs handle this without trouble, but older computers or those with limited RAM may experience lag or stuttering in both games.

Before you start, check your PC's available RAM. Open Task Manager by pressing Ctrl+Shift+Esc, click the Performance tab, and look at the Memory section. If you have less than 4 GB of RAM available (not total—available), both games may lag noticeably. Roblox typically uses 500 MB to 1 GB per instance, so two games can consume 1 to 2 GB of your available memory.

If your PC struggles, close other programs before playing. Shut down web browsers you are not using, close Discord, Spotify, or other background apps, and disable browser extensions that consume memory. This frees up RAM for the two Roblox games and usually improves performance significantly.

Controlling both games and switching between windows

When both games are running, you control whichever window is in focus—the one you clicked on most recently. Click on the other game window to switch control to it. The first game continues running in the background, so your character does not stop moving or disappear just because you switched focus.

If you have resized both windows to sit side by side, you can see both games at once and click between them easily. If one window is maximized, you can use Alt+Tab to switch between them quickly, or click the game window in your taskbar to bring it to the front.

Keep in mind that if either game requires you to type (chat, entering a code, typing a username), you need to make sure that window is in focus first. Typing in the wrong window will send your message or input to the wrong game.

Troubleshooting when one account logs out unexpectedly

If you are using two browser tabs or windows in the same browser and one account logs out when you log into the other, you are running into the browser's single-session limitation. Switch to using two different browsers instead. For example, use Chrome for account one and Firefox for account two.

If you are using the Roblox app on two separate Windows user accounts and one account logs out, make sure you are actually logged into the correct Windows user account. Switch user accounts using the Windows user menu in the bottom left corner of the taskbar, then open the Roblox app again. The app should remember your login for that Windows user.

If a game crashes or closes unexpectedly, you can reopen it without affecting the other game. straightforward launch Roblox again in the same browser or app, and the other game continues running in its window.

Frequently Asked Questions

Do I need two copies of Roblox installed?

No. One copy of the Roblox app can be used by multiple Windows user accounts, and web browsers do not require installation at all. You only need two different browsers or two Windows user accounts to keep two logins separate.

Will playing two games at once get my accounts banned?

No. Roblox does not ban accounts for running multiple games on the same PC. The game does not detect or care how many instances are running. However, each account must follow Roblox's terms of service in the games you play—multi-accounting is only against the rules in specific games that explicitly forbid it, and you would know from the game's rules if that applies.

Can I use two monitors to play both games full screen?

Yes. If your PC has two monitors connected, you can maximize one game on each monitor and control them by clicking between them or using Alt+Tab. This gives you a full-screen view of both games at once, which is ideal if your PC has the processing power to handle it smoothly.

What if I only have one web browser installed?

You can read a second browser for free. Chrome, Firefox, Edge, and Opera are all free and available from their official websites. Once installed, use one for each account. You do not need to uninstall your current browser—multiple browsers can coexist on the same PC.

Will both games run if I minimize one?

Yes. Minimizing a game window does not stop it from running. Both games continue to run in the background whether they are visible or minimized. However, minimized games may run more slowly or pause certain animations to save processing power, depending on the game and your PC settings.
