Trust Another Player with Container Access
Open Trust Management
Sneak (hold Shift) and right-click on one of your protected containers. A trust menu will appear showing the container's current access list.
Add a Trusted Player
Look for an option to add a new trusted player (often a button or text input field). Enter the exact username of the player you want to trust. Confirm the addition.
What Trusted Players Can Do
Once added to your trust list, that player can open, take items from, and add items to your container just as if it were their own. They cannot, however, change who else has access—only you (the owner) control the trust list.
Remove Trust
Return to the trust menu and select the player's name to remove them. They will immediately lose access to that container.
Multiple Containers
You must add trust separately for each container. Trusting someone with one chest doesn't automatically grant access to your other containers.
