I'm attempting to password protect EDITING of the grub menu on boot. I've generated a hash for the password with
grub-mkpasswd-pbkdf2 and entered the following in the
set superusers="grubadmin" password_pbkdf2 grubadmin grub.pbkdf2.sha512.10000.874B9326A498Y237D4923.....
Then, after I ran
update-grub and rebooted.. I noticed that even automatically booting into the default kernel is asking for a password. I was under the impression that this password is only for EDITING the grub menu, which is what I want to accomplish. The server should boot into the default kernel without a password requirement. What am I doing wrong? I am running Ubuntu 14.04.5.
