Chests with passwords

I would like to see password protected chests added to Minecraft. I often play multiplayer games on Realms. Sometimes the contents of my chest get stolen. This means you can't play with peace of mind. That's when I came up with this "chest with a password." I think the following specifications are easy to use. 1. First, craft and place a chest with a password. 2. The first time you open this chest, you will be prompted to set a password. Once a password is set, it cannot be changed. 3.From the second time onwards, when you try to open it, a password entry screen will appear, and you will not be able to open the chest unless you enter the correct password. It looks like this. I also think it would be even more useful if they slightly changed the color or texture so that it could be distinguished from a normal chest. Also, I'm sorry to ask for so many things, but I would be grateful if it were possible to connect two Chests with passwords together to make a larger chest. However, this is something I came up with as an amateur, so I think there may be various inconveniences for the people who run Minecraft. So, if you would like to adopt this idea, I don't mind if you change the specifications a little, and I would be very happy if you would adopt it. Also, I am Japanese. This text was written using a translation function, so it may be difficult to understand. I apologize. Thank you for reading this long article to the end. I'm looking forward to the new Minecraft updates.
