Although passwords can be encrypted, they can be edited and modified. What command can be used to prohibit this function?

The `password` command needs to be used together with the `lock` command.

When the `lock` command is executed, it displays a password input interface, requiring the user to provide a password. If the user fails to provide the correct password, the execution result of the `lock` command is an error, and then subsequent commands cannot be executed.

You can place the `password` command before `title`, so that the entire menu will be protected. Unless you enter `p` as prompted on the screen and provide the correct password (which is equivalent to unlocking), all menu items cannot be changed. But at this time, the user can execute all the menu items in your existing menu. Unless you use `lock` to lock a certain menu, the user will not be able to execute the commands in the corresponding menu.

Note that it is more appropriate to place `lock` in the first statement after `title`, because only when the program executes to `lock` will it prevent the user from further execution. You lock all the menu items that need to be protected, that is, after each `title` line, a `lock` is needed, otherwise, the menu item is not protected and the user can execute it.

Thank you, the second-floor owner. I will try the settings you mentioned later.

Hehe, the second-floor landlord.
The brother above still doesn't know that this second-floor landlord is currently the main author of grub4dos :)
