A Roblox inventory can show avatar items, badges and other assets owned by an account. Making it public is useful for some collectors and traders, but most younger players do not need strangers to see everything they own.
Privacy settings and available categories change, so review the live account rather than relying on an old menu guide.
What public visibility can reveal
Other users may see valuable limited items, game badges and interests. That can attract trade offers, impersonation attempts or messages designed around something the child owns.
An inventory does not normally reveal a password, but it gives a scammer better information for a convincing approach.
When public access has a purpose
Older users who trade eligible limited items may intentionally show parts of an inventory. Creators may also need public assets for development or portfolio work.
Those are specific uses, not a reason to leave every child's inventory open by default. Plus and trading features can also have age and safety requirements.
A practical family choice
Keep the inventory private or limited when the child does not use a feature that needs public visibility. Review the setting before any trading begins.
Whatever the choice, teach the child that an item owner does not need to prove ownership by sharing a login, cookie, backup code or screen-control access.
Check the setting again after a major account or Marketplace update, because Roblox can reorganise privacy options over time.
