Per this post,I know it's easy to change password when boot GRUB.
When I read set debian grub password ,I run command as below:
cat << EOF >> /boot/grub/menu.lst
timeout 3
password hackme
EOF
But it doesn't work,I can still change password when boot GRUB,without input hackme
.
How to avoid password change when boot GRUB in debian 10 system?
