Frequently Asked Questions

Everything you need to know

How do I find my .ROBLOSECURITY cookie? ▼
For Chrome/Edge:
  1. Go to roblox.com and make sure you're logged in
  2. Press F12 to open Developer Tools
  3. Click the Application tab (or Storage in Firefox)
  4. Expand Cookies → https://www.roblox.com
  5. Find the cookie named .ROBLOSECURITY
  6. Copy the full value (starts with _|WARNING:-DO-NOT-SHARE-THIS...)
⚠️ NEVER share this cookie with anyone! It gives full access to your account.
Is CookieDefender safe to use? ▼
Yes! CookieDefender is completely safe and uses zero-knowledge architecture. We never store or transmit your cookies. All protection happens locally on your machine. Your .ROBLOSECURITY token never leaves your device.
Does it work on Windows 10 and 11? ▼
Absolutely! CookieDefender is optimized for both Windows 10 (64-bit) and Windows 11. It's a portable executable with no installation needed. Simply download and run.
Will Roblox ban me for using this? ▼
No. CookieDefender is purely a defensive security tool. It doesn't modify game files, inject code, or interact with Roblox's anti-cheat systems. It only protects your authentication cookies from being stolen.
How does it protect against cookie loggers? ▼
CookieDefender uses HMAC-SHA256 cryptographic binding to tie your cookies to your unique hardware fingerprint. Even if a logger steals your cookie, it cannot be used on another machine because the hardware signature won't match.
What should I do if my cookie gets stolen? ▼
If you suspect your cookie has been compromised:
  1. Immediately log out of all Roblox sessions
  2. Change your password at roblox.com/settings
  3. Enable 2-Step Verification in Security settings
  4. Run CookieDefender to secure your new session
  5. Check account activity for unauthorized purchases or changes
Is it free? ▼
Yes! CookieDefender is 100% free and open-source. No hidden fees, no premium versions, no subscriptions. We believe account security should be accessible to everyone.
