Hi all,

I want to authenticate for login in Single user mode (unauthorized access and not able to change the root password).How it can possible?
And second to set GRUB password on running system.

Thanks,

Setting a password to grub will solve the problem. If you are concern about security, then physical security should be your first issue. If the attacker has physical access to your host, then nothing will stop him to access the system.
