Roblox Account Manager

A Chrome/Edge extension (Manifest V3) to save unlimited Roblox accounts and switch between them in one click. It works by saving and swapping your .ROBLOSECURITY session cookie — the same thing that keeps you logged in.

Install on Chrome / Edge (unpacked)

1. Open chrome://extensions (or edge://extensions).
2. Turn on Developer mode (top-right).
3. Click Load unpacked and select this roblox-account-manager folder.
4. Pin the red R icon from the puzzle-piece menu so it's always visible.

Install on Firefox (.xpi)

The packaged file is roblox-account-manager.xpi

Firefox blocks permanent install of unsigned add-ons on the normal Release/Beta builds — this is a Mozilla security rule, not something the extension can opt out of. Pick one:

• Try it now (any Firefox), removed on restart: go to about:debugging#/runtime/this-firefox
  • Load Temporary Add-on - select roblox-account-manager.xpi.
• Permanent, no signing: use Firefox Developer Edition, Nightly, or ESR. In about:config set xpinstall.signatures.required to false, then open about:addons
  • gear icon - Install Add-on From File - pick the .xpi.

How to use

1. Log into a Roblox account normally at roblox.com.
2. Open the extension and click + Save current. Your username and avatar are stored.
3. Log out, log into a different account, and + Save current again. Repeat for as many accounts as you like.
4. To switch, just click Switch on any saved account, open Roblox tabs reload into that account automatically.

Adding an account without logging in

Open “Add account manually” and paste a .ROBLOSECURITY cookie value. The account's name/avatar resolves the first time you switch to it.

Backup

Use Export to save all accounts to a JSON file, and Import to restore them (handy when moving to a new machine). Keep this file private.

How it works

• The extension reads/writes the .ROBLOSECURITY cookie on .roblox.com using the cookies permission.
• Accounts are stored locally in chrome.storage.local, nothing is sent anywhere.
• Switching sets the cookie to the chosen account's value and reloads Roblox tabs.

Security!

The .ROBLOSECURITY cookie is a full session token. Anyone who obtains it can access your account without a password or 2FA. Because of that:

• Never share your export file or paste your cookie anywhere else.
