I figured out my error. I had a typo in my 40_custom file and forgot to run grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg when I added the second user. For anyone that finds this message trying to solve this issue the correct syntax is: set superusers="user1", "user2" password_pbkdf2 user1 /hash1/ password_pbkdf2 user2 /hash2/ On 11/11/18 1:34 PM, Dr. Zenzic wrote: > > Hello All, > > I am trying to set multiple users with passwords for modifying grub2 > menu entries at boot.
