You generally can’t sell a Roblox Limited item without the required two- step/security setup. Roblox’s support says reselling Limited and Limited U items requires a membership, and users report that the authenticator / 2-step prompt is not bypassable.

What you need

  • Roblox Premium membership.
  • An item that is actually marked as Limited or Limited U.
  • Two-step verification / authenticator enabled before the sale action will go through.

Legit options

  1. Turn on 2-step verification or an authenticator, then list the item normally.
  1. If the item is not Limited, you cannot resell it as a marketplace item.
  1. If you’re trying to sell something you created, Roblox treats that differently from reselling a Limited item.

Important

Trying to bypass the security prompt is not a supported path, and the sources I found consistently say there is no workaround.

CaseCan you sell?
Limited / Limited U with Premium and 2-step enabledYes
Limited item without 2-step / authenticatorNo
Non-Limited itemNo, not as a resale listing
[1][2] Bottom line: the safe and supported fix is to enable 2-step verification, not to look for a bypass.
