You usually can’t disable “Xbox security” inside Roblox itself ; the block is coming from Xbox privacy/family settings tied to the Microsoft account used on the Microsoft Store version of Roblox. The fix is to change the Xbox privacy settings for that Microsoft account, or unlink the Xbox account from Roblox if it was connected.

What to change

On the Xbox/Microsoft account, look for:

  • Privacy & online safety
  • View details & customize
  • Communication and multiplayer
  • Xbox privacy settings

The setting that most often blocks Roblox is multiplayer/chat access, not Roblox login itself. Microsoft’s Xbox privacy controls are managed from the account/family settings area, and Roblox’s own help pages show that Xbox- linked accounts can also be disconnected from Roblox security settings.

Steps to try

  1. Sign in with the Microsoft account used on the Xbox/Microsoft Store.
  2. Open Xbox privacy or Privacy & online safety.
  3. Set the multiplayer and communication permissions to allow play.
  4. If the account is a child account, change it from the family settings or ask the family organizer to approve it.
  5. In Roblox, check Security and disconnect Xbox if needed, then sign in again.

If you want Roblox to stop using Xbox login

You can unlink the Xbox connection from Roblox:

  • In Roblox on Xbox, go to Settings > Account > Unlink.
  • Or on the Roblox website, go to Settings > Security and disconnect the Xbox account.

Microsoft Store note

If you’re using the Microsoft Store version, Microsoft also notes that Store sign-in and account settings can affect device access and purchases, so the Microsoft account used on the PC matters too.

Common reason it still blocks

Even after changing Xbox settings, Roblox may still be blocked if:

  • The Microsoft account is under family restrictions.
  • The Roblox account has age-based restrictions.
  • The Xbox account was re-linked automatically after signing back in.

Best fix path

The fastest route is usually:

  1. Change Xbox privacy settings.
  2. Check family controls.
  3. Unlink and relink Roblox only if needed.

TL;DR: You don’t disable “Xbox security” inside Roblox; you loosen the Microsoft/Xbox privacy controls that are enforcing the block, then relaunch Roblox and test again.
