= Setting a password for interactive edit mode

If you wish to protect the *GRUB2* interactive edit mode with a password, but allow ordinary users to boot the computer, you have to create a definition file where you set up this functionality: 

.Procedure

. Create the `/etc/grub.d/01_users` file and write the following lines into the file.
+
----
set superusers="root"
export superusers
password root <password>
----

. Regenerate the *GRUB2* configuration file and reinstall the bootloader into the MBR, as described in xref:adding-other-operating-systems-grub2[Adding other operating systems to the *GRUB2* menu].


.More information

You can encrypt the password by using *pbkdf2*. Use `grub2-mkpasswd-pbkdf2` to encrypt the password, then replace the password line with:

----
password_pbkdf2 root grub.pbkdf2.sha512.10000.1B4BD9B60DE889A4C50AA9458C4044CBE129C9607B6231783F7E4E7191D8254C0732F4255178E2677BBE27D03186E44815EEFBAD82737D81C87F5D24313DDDE7.E9AEB53A46A16F30735E2558100D8340049A719474AEEE7E3F44C9C5201E2CA82221DCF2A12C39112A701292BF4AA071EB13E5EC8C8C84CC4B1A83304EA10F74
