I set up the GRUB password protection on my Ubuntu LTS 14 64bits. To do that I generated a hash of the password with grub-mkpasswd-pbkdf2. Then I edited /etc/grub.d/40_custom to add those 2 lines:
set superusers="admin" password_pbkdf2 admin grub.pbkdf2.sha512.10000.EC81D.............After updating the Grub and rebooting, the password is present BUT everywhere. If I want to boot on Ubuntu, I have to enter my password. I’d like to set up the password only for ‘e’ editing GRUB menu. (to avoid single user mode)
Any Ideas ?
Thanks
Answer
I just found the solution.
I just need to add the unrestricted attribute to the menuentry in 10_linux file as described here:

It will keep the password while editing.
