If the system does not require valid authentication before it boots into single-user or maintenance mode, anyone who invokes single-user or maintenance mode is granted privileged access to all files on the system. GRUB 2 is the default boot loader for RHEL 8 and is designed to require a password to boot into single-user mode or make modifications to the boot menu.


Configure the system to require a grub bootloader password for the grub superusers account with the grub2-setpassword command, which creates/overwrites the /boot/grub2/user.cfg file.

Generate an encrypted grub2 password for the grub superusers account with the following command:

$ sudo grub2-setpassword
Enter password:
Confirm password:
